Clinical Problem Solving 245 Disturbances of Ocular Movement Nystagmus, which is essentially an ataxia of the ocular muscles, is a rhythmical oscillation of the eyes. It is more easily demonstrated when the eyes are deviated in a horizontal direction. This rhythmic oscillation of the eyes may be of the same rate in both directions (pendular nystagmus) or quicker in one direction than in the other (jerk nystagmus). In the latter situation, the movements are referred to as the slow phase away from the visual object, followed by a quick phase back toward the target. For example, a patient is said to have a nystagmus to the left if the quick phase is to the left and the slow phase is to the right. The movement of nystagmus may be confined to one plane and may be horizontal or vertical, or it may be in many planes when it is referred to as rotatory nystagmus. The posture of the eye muscles depends mainly on the normal functioning of two sets of afferent pathways. The first is the visual pathway whereby the eye views the object of interest,and the second pathway is much more complicated and involves the labyrinths, the vestibular nuclei, and the cerebellum. Cerebellar Syndromes Vermis Syndrome the most common cause of vermis syndrome is a medulloblastoma of the vermis in children. Involvement of the flocculonodular lobe results in signs and symptoms related to the vestibular system. Since the vermis is unpaired and influences midline structures, muscle incoordination involves the head and trunk and not the limbs. Cerebellar Hemisphere Syndrome Tumors of one cerebellar hemisphere may be the cause of cerebellar hemisphere syndrome. The symptoms and signs are usually unilateral and involve muscles on the side of the diseased cerebellar hemisphere. Disorders of the lateral part of the cerebellar hemispheres produce delays in initiating movements and inability to move all limb segments together in a coordinated manner but show a tendency to move one joint at a time. Disorders of Speech Dysarthria occurs in cerebellar disease because of ataxia of the muscles of the larynx. Although muscle hypotonia and incoordination may be present, the disorder is not limited to specific muscles or muscle groups; rather, an entire extremity or the entire half of the body is involved. If both cerebellar hemispheres are involved, then the entire body may show disturbances of muscle action. Even though the muscular contractions may be weak and the patient may be easily fatigued, there is no atrophy. Common Diseases Involving the Cerebellum One of the most common diseases affecting cerebellar function is acute alcohol poisoning. The following frequently involve the cerebellum: congenital agenesis or hypoplasia, trauma, infections, tumors, multiple sclerosis, vascular disorders such as thrombosis of the cerebellar arteries, and poisoning with heavy metals. The many manifestations of cerebellar disease can be reduced to two basic defects: hypotonia and loss of influence of the cerebellum on the activities of the cerebral cortex. A 10-year-old girl was taken to a neurologist because her parents had noticed that her gait was becoming awkward. Six months previously, the child had complained that she felt her right arm was clumsy, and she had inadvertently knocked a teapot off the table. More recently, her family had noticed that her hand movements were becoming jerky and awkward; this was particularly obvious when she was eating with a knife and fork. The mother commented that her daughter had had problems with her right foot since birth and that she had a clubfoot. The mother said she was particularly worried about her daughter because two other members of the family had similar signs and symptoms. On physical examination, the child was found to have a lurching gait with a tendency to reel over to the right. When the strength of the limb muscles was tested, those of the right leg were found to be weaker than those of the left leg. She had severe pes cavus of the right foot and a slight pes cavus of the left foot.

It is bounded on all sides by tubular and vascular basement membranes and is filled with cells, extracellular matrix, and interstitial fluid (1). Its distribution varies within the kidney; it accounts for approximately 8% of the total parenchymal volume in the cortex and up to 40% in the inner medulla (6,7). The term "renal interstitium" is often inadequately used to refer to the peritubular interstitium (the space between tubules, glomeruli, and capillaries); the periarterial connective tissue and the extraglomerular mesangium are considered specialized interstitia (1). It is debated whether microvessels and capillaries, which are located within the peritubular space, are actually part of the renal interstitium or just run through it (1). The tubular interstitium in the cortex and medulla differ with regard to their cellular constituents, extracellular matrix composition, relative volume, and endocrine function, justifying the consideration of cortical and medullary interstitium as separate entities. The intertubular interstitium harbors dendritic cells, macrophages, lymphocytes, lymphatic endothelial cells Fibroblasts typically are embedded within the fibrillar matrix of connective tissues and are considered prototypical mesenchymal cells. Renal fibroblasts anastomose with each other, forming a continuous network in cortex and medulla (8). Fibroblasts can acquire an activated phenotype with a relatively large oval nucleus with one or two nucleoli, abundant rough endoplasmatic reticulum, and several sets of Golgi apparatus; this reflects their capacity to synthesize substantial amounts of extracellular matrix constituents (12). Under physiologic conditions, however, adult fibroblasts are relatively inactive, the endoplasmatic reticulum is reduced, and the nucleus is flattened and heterochromatic. On the basis of their appearance, it was assumed that the primary function of renal fibroblasts was to provide structural support to nephrons through deposition of extracellular matrix and through direct cell-cell interactions (1). In addition, fibroblasts play an important role in maintaining vascular integrity in close association with vessels (then typically referred to as vascular smooth muscle cells and pericytes) (13,14). Finally, fibroblasts have been identified as sources of Epo and renin in the kidney (15,16). It is obvious that such diverse functions are not fulfilled by one cell type but that renal fibroblasts are instead a heterogeneous cell population with distinct functions.

The photomicrograph displays a cortical section of a paraffin-fixed periodic acid-Schiff­ stained mouse kidney. Arrows (black) point to interstitial fibroblasts or to microvessels, respectively (green). Glomerular and tubular cross-sections and contents of the interstitium are illustrated in the schematic. The interstitial compartment contains non­hormone-producing fibroblasts (blue), microvessels (red), perivascular cells (green), renin-producing perivascular cells (orange), juxtaglomerular cells (lilac), and erythropoietin (Epo)-producing fibroblasts (pink). Heterogeneity of Renal Fibroblasts Our current knowledge of fibroblast heterogeneity evolved from morphologic descriptions to immunophenotyping, and only recently the use of transgenic mouse models provided insights into origins and functions of renal fibroblasts. Ultrastructural analysis first revealed that cortical fibroblasts differ from medullary fibroblasts, as they form a finer network through their radiating cytoplasmatic processes with tubular cells, endothelial cells, and each other. Furthermore, medullary fibroblasts often have a stouter appearance and harbor cytoplasmatic lipid droplets (8). However, such ultrastructural analysis revealed little about distinct functions of fibroblast populations (1,2,8,17). Attempts to link ultrastructural appearance to function were followed by studies that aimed to define renal fibroblast populations through use of fibroblast markers. Clearly, all proposed markers had deficiencies, creating an as-yet unresolved dispute in the field regarding identity of fibroblasts and their respective function in kidney health and disease. The confusion is further fueled by assumed different origins of fibroblasts in diseased kidneys (for extensive information, see elsewhere [4,29]). For practical purposes, we here define fibroblasts as the nonvascular, nonepithelial, and noninflammatory cell constituents of the kidney (11).

But this experience may or may not be a real solution to the problem ­ it needs to be verified and tested impotence grounds for divorce generic super avana 160 mg mastercard. It may then need further elaboration and development before it is put to use or shared with other people erectile dysfunction protocol does it work order super avana on line. On his 70th birthday celebration erectile dysfunction treatment without medication purchase generic super avana pills, Hermann Ludwig Ferdinand von Helmholtz offered his thoughts on his creative process reasons erectile dysfunction young age super avana 160 mg otc, consistent with the Wallas Stage Model. Poincare speculated that what happened was that once ideas were internalised, they bounced around in the subconscious somewhat like billiard balls, colliding with each other ­ but occasionally interlocking to form new stable combinations. When this happened and there was a significant fit, Poincare speculated that the mechanism which identified that a solution to the problem had been found was a sort of aesthetic sense, a "sensibility. It may be surprising to see emotional sensibility evoked a propos of mathematical demonstrations which, it would seem, can only be of interest to the intellect. This would be to forget the feeling of mathematical beauty, of the harmony of numbers and forms, of geometric elegance. This is a true aesthetic feeling that all real mathematicians know, and surely it belongs to emotional sensibility. Poincare argued that in the subconscious, "the useful combinations are precisely the most beautiful, I mean those best able to charm this special sensibility that all mathematicians know. The conscious and subconscious mental faculties sort and internalize this information by making patterns and associations between them and developing a "sense" of how new pieces of information "fit" with patterns, rules, associations and so forth that have already been internalized and may or may not even be consciously understood or brought into awareness. Incubation Incubation is the concept of "sleeping on a problem," or disengaging from actively and consciously trying to solve a problem, in order to allow, as the theory goes, the unconscious processes to work on the problem. Incubation can take a variety of forms, such as taking a break, sleeping, or working on another kind of problem either more difficult or less challenging. Findings suggest that incubation can, indeed, have a positive impact on problem-solving 168 Cognitive Psychology ­ College of the Canyons outcomes. Problem Solving Experts With the term expert we describe someone who devotes large amounts of his or her time and energy to one specific field of interest in which he, subsequently, reaches a certain level of mastery. It should not be of surprise that experts tend to be better in solving problems in their field than novices (people who are beginners or not as well trained in a field as experts) are. They are faster in coming up with solutions and have a higher success rate of right solutions. But what is the difference between the way experts and non-experts solve problems? Research on the nature of expertise has come up with the following conclusions: 1. Knowledge: An experiment by Chase and Simon (1973a, b) dealt with the question how well experts and novices are able to reproduce positions of chess pieces on chessboards when these are presented to them only briefly. The results showed that experts were far better in reproducing actual game positions, but that their performance was comparable with that of novices when the chess pieces were arranged randomly on the board. Chase and Simon concluded that the superior performance on actual game positions was due to the ability to recognize familiar patterns: A chess expert has up to 50,000 patterns stored in his memory. In comparison, a good player might know about 1,000 patterns by heart and a novice only few to none at all. This very detailed knowledge is of crucial help when an expert is confronted with a new problem in his field. Chi and her co-workers took a set of 24 physic problems and presented them to a group of physics professors as well as to a group of students with only one semester of physics. As it turned out the students tended to group the problems based on their surface structure (similarities of objects used in the problem. By recognizing the actual structure of a problem experts are able to connect the given task to the relevant knowledge they already have. Analysis: Experts often spend more time analyzing a problem before actually trying to solve it. This way of approaching a problem may often result in what appears to be a slow start, but in the long run this strategy is much more effective. A novice, on the other hand, might start working on the problem right away, but often has to realize that he reaches dead ends as he chose a wrong path in the very beginning.

The foramen magnum occupies the central area of the floor and transmits the medulla oblongata and its surrounding meninges erectile dysfunction over 40 order super avana 160 mg visa,the ascending spinal parts of the accessory nerves erectile dysfunction drugs boots order super avana uk, and the two vertebral arteries erectile dysfunction beat filthy frank purchase super avana 160 mg line. The hypoglossal canal is situated above the anterolateral boundary of the foramen magnum for erectile dysfunction which doctor to consult discount super avana line. The jugular foramen lies between the lower border of the petrous part of the temporal bone and the condylar part of the occipital bone. It transmits the following structures from before backward: the inferior petrosal sinus; the 9th, 10th, and 11th cranial nerves; and the large sigmoid sinus. The inferior petrosal sinus descends in the groove on the lower border of the petrous part of the temporal bone to reach the foramen. The sigmoid sinus turns down through the foramen to become the internal jugular vein. It transmits the vestibulocochlear nerve and the motor and sensory roots of the facial nerve. The internal occipital crest runs upward in the midline posteriorly from the foramen magnum to the internal occipital protuberance; to it is attached the small falx cerebelli over the occipital sinus. On each side of the internal occipital protuberance is a wide groove for the transverse sinus. This groove sweeps around on either side, on the internal surface of the occipital bone, to reach the posteroinferior angle or corner of the parietal bone. The groove now passes onto the mastoid part of the temporal bone; at this point, the transverse sinus becomes the sigmoid sinus. The superior petrosal sinus runs backward along the upper border of the petrous bone in a narrow groove and drains into the sigmoid sinus. As the sigmoid sinus descends to the jugular foramen, it deeply grooves the back of the petrous bone and the mastoid part of the temporal bone. Table 5-1 provides a summary of the more important openings in the base of the skull and the structures that pass through them. Mandible the mandible, or lower jaw, is the largest and strongest bone of the face, and it articulates with the skull at the temporamandibular joint. The body of the mandible meets the ramus on each side at the angle of the mandible. Introduction to the Brainstem the brainstem is made up of the medulla oblongata, the pons, and the midbrain and occupies the posterior cranial fossa of the skull. It is stalklike in shape and connects the narrow spinal cord with the expanded forebrain (see Atlas Plates 1­8). The brainstem has three broad functions: (1) it serves as a conduit for the ascending tracts and descending tracts connecting the spinal cord to the different parts of the higher centers in the forebrain; (2) it contains important reflex centers associated with the control of respiration and Table 5-1 Summary of the More Important Openings in the Base of the Skull and the Structures That Pass Through Them Bone of Skull Structures Transmitted Opening in Skull Anterior Cranial Fossa Perforations in cribriform plate Middle Cranial Fossa Ethmoid Olfactory nerves Optic canal Superior orbital fissure Lesser wing of sphenoid Between lesser and greater wings of sphenoid Greater wing of sphenoid Greater wing of sphenoid Greater wing of sphenoid Between petrous part of temporal and sphenoid Foramen rotundum Foramen ovale Foramen spinosum Foramen lacerum Optic nerve, opthalmic artery Lacrimal, frontal, trochlear oculomotor, nasociliary, and abducent nerves; superior ophthalmic vein Maxillary division of the trigeminal nerve Mandibular division of the trigeminal nerve, lesser petrosal nerve Middle meningeal artery Internal carotid artery Posterior Cranial Fossa Foramen magnum Occipital Hypoglossal canal Jugular foramen Occipital Between petrous part of temporal and condylar part of occipital Petrous part of temporal Internal acoustic meatus Medulla oblongata, spinal part of accessory nerve, and right and left vertebral arteries Hypoglossal nerve Glossopharyngeal, vagus, and accessory nerves; sigmoid sinus becomes internal jugular vein Vestibulocochlear and facial nerves Gross Appearance of the Medulla Oblongata 197 Tentorium cerebelli Midbrain Inferior colliculus Trochlear nerve Superior colliculus Trigeminal nerve Facial and vestibulocochlear nerves Transverse sinus Fourth ventricle Medulla oblongata Gracile tubercle Margin of foramen magnum Transverse process of atlas Glossopharyngeal, vagus, and accessory nerves Spinal part of accessory nerve Vertebral artery Second cervical spinal nerve Transverse process of axis Spinal cord Ligamentum denticulatum Vertebral artery Figure 5-8 Posterior view of the brainstem after removal of the occipital and parietal bones and the cerebrum, the cerebellum, and the roof of the fourth ventricle. Gross Appearance of the Medulla Oblongata the medulla oblongata connects the pons superiorly with the spinal cord inferiorly. The junction of the medulla and spinal cord is at the origin of the anterior and posterior roots of the first cervical spinal nerve, which corresponds approximately to the level of the foramen magnum. The medulla oblongata is conical in shape, its broad extremity being directed superiorly. The central canal of the spinal cord continues upward into the lower half of the medulla; in the upper half of the medulla, it expands as the cavity of the fourth ventricle. On the anterior surface of the medulla is the anterior median fissure,which is continuous inferiorly with the anterior median fissure of the spinal cord. The pyramids are composed of bundles of nerve fibers, called corticospinal fibers, which originate in large nerve cells in the precentral gyrus of the cerebral cortex. The pyramids taper inferiorly, and it is here that the majority of the descending fibers cross over to the opposite side, forming the decussation of the pyramids. Posterolateral to the pyramids are the olives, which are oval elevations produced by the underlying inferior olivary nuclei. In the groove between the pyramid and the olive emerge the rootlets of the hypoglossal nerve. In the groove between the olive and the inferior cerebellar peduncle emerge the roots of the glossopharyngeal and vagus nerves and the cranial roots of the accessory nerve. The posterior surface of the superior half of the medulla oblongata forms the lower part of the floor of the fourth ventricle. The posterior surface of the inferior half of the medulla is continuous with the posterior aspect of the spinal cord and possesses a posterior median sulcus. On each side of the median sulcus, there is an elongated swelling, the gracile tubercle, produced by the underlying gracile nucleus.
