Pathology polio

In poliomyelitis mainly affects motor neurons anterior horns of the spinal cord. Often there are also inflammatory changes in the motor nuclei of the cranial nerves, brain stem, the nuclei of the midbrain and the anterior central gyrus cortex. Meninges swollen, red-blooded. Gyrus somewhat flattened. The substance of the brain, especially the spinal cord (in the lumbar, thoracic and cervical enlargement) and medulla - flabby, gelatinous, full-blooded, with diapedetic hemorrhages. Pattern of gray matter cleared on the cut surface it sinks, and white - protrudes. In tonsils, mesenteric lymph Read more [...]

State of the anterior abdominal wall

Assessment of the anterior abdominal wall is important in the diagnosis of acute surgical diseases abdominal cavity. The first thing you notice is any swelling of the stomach or the fall and their participation in the breath. As a rule, in the painful area is seen limiting trips abdominal wall compared with healthy portions. With the spread of the entire anterior abdominal wall can hardly participate in the breath and it becomes only diaphragmatic. An example of this condition are the first hours of peritonitis. Sunken abdomen with a small protrusion in the epigastric region, the presence of Read more [...]

Impotence caused by endocrine disorders

The reason sexual weakness may serve as a weakening or complete cessation of the hormonal activity of the testicles - hypogonadism. This disorder can be primary and secondary. Primary hypogonadism caused by congenital hypoplasia, trauma, inflammatory diseases of the testes. In secondary - testicular function violated by diseases of other endocrine glands and central nervous system. The influence of endocrine glands on sexual function can be traced very clearly with their diseases. So disease thyroid cancer in early childhood leads, as a rule, to underdevelopment of gonads and adrenal tumors, Read more [...]

Thoracic cavity

Thoracic cavity (Deleted anterior chest wall): 1 - aortic arch, 2 - pulmonary trunk, 3 - left phrenic nerve, 4 - pericardium, 5 - pleura, b - right lung 7 - upper hollow Vienna. Thoracic cavity (cavum thoracis) lies within the chest, but at the top of a bit beyond its limits, speaking base of the neck (above the level I ribs). From below thoracic cavity limited aperture (see). Capacity of the chest is different depending on the growth and build of the man, it is continuously and dramatically change with respiratory movements. In the cavity of the chest to the left and to the right are the Read more [...]

Progressive muscular atrophy verdnigagofmana

Refers to the earliest form of systemic degenerative diseases of childhood. First described by Werdnig (G. Werdnig) and Hoffman (J. Hoffmann). Currently, there is a clear clinical characteristics of the disease, while its etiology and pathogenesis remain unknown. Disease a hereditary origin with autosomal recessive type of transmission (see Genetics). Of interest is the fact that the sick children in the same family are often the same sex. Pathology of the disease is reduced to degenerative anterior horn cells of the spinal cord with secondary degeneration of motor fibers anterior roots and Read more [...]

The third ventricle of the brain

The third ventricle of the brain (Ventriculus tertius) represents the residual space of diencephalon diencephalon) and contains the cerebrospinal fluid. It is shaped slit covered ependymomas (Fig. 469), limited to the walls: 1) lateral - medial surface of the thalamus, and 2) the front - a set of columns (columnae fornicis), anterior commissure of the brain (commissura cerebri anterior) and Border plate, B) back - Spike leashes pineal brain back soldering brain, and 4) the bottom - the hypothalamus and the posterior perforated substance of the brain, and 5) the top-ependymal plate surrounding Read more [...]

Spinotalamichesky way

1. Spinotalamichesky way divided into lateral and anterior (tr. spinothalamicus lateralis et anterior) (Fig. 496). Contains fibers conducting impulses from the skin receptors that perceive tactile, thermal and pain sensitivity of all parts of the body except the skin and organs of the facial part of the head. From skin irritation seen similar receptors of trigeminal nerve. First neuron spinotalamicheskogo way unipolar forms, located in the intervertebral site. Its dendrites are free nerve endings (feel pain), calf Krause (perceive cold), Ruffini corpuscles (perceived warmth). Axons in the Read more [...]

Spinal nerves

Spinal nerves (Nn. spinales), mixed nerve structures, including motor, sensory and autonomic fibers. Depending on their exit from the spinal column are divided into five groups: 8 cervical (nn. cervicales), 12 thoracic (nn. thoracici), 5 lumbar (nn. lumbales), 5 sacral (nn. sacrales) and 1 coccygeal (n. coccygeus). Only 31 pairs of nerves. Spinal nerves formed by connecting the peripheral sensory fibers posterior spinal root, sprouting motor cells anterior spinal columns, which form anterior spinal root, and sympathetic postganglionic fibers. In this case, each segment of the spinal cord corresponding Read more [...]

Spinal cord-3

Front cord. Formed in four ways and white anterior commissure. 1.       Front corticospinal way (Tr. corticospinalis anterior) basically starts from the pyramidal cells of the anterior central gyrus of the cerebral cortex. Descends the brainstem neperekreschivayas, reaching the spinal cord, where each segment goes to the opposite side. 2.       Front spino-thalamic way (Tr. spinothalamicus anterior) is located lateral to the previous path and in front of the anterior column of gray matter. Formed fibers crossed beam rear pillar cells spinal cord. Ends in the thalamus. 3. Vestibular-spinal Read more [...]

Spinal cord-1

The nuclei of gray matter. In the posterior columns (Fig. 459) distinguish the superficial marginal zone (zona terminalis), consisting of a small nerve cells, more deeply located spongy substance (substantia spongiosa), formed by the two-stream cells, whose axons are in the white matter and combined into pathways. On these routes are conducted nerve impulses from the nuclei of the spinal cord in its other segments or head brain. Sponge substance covered with a gelatinous substance (substantia gelatinosa), consisting of a small nerve and glial cells, and then have our own core rear pillar (nucll. Read more [...]

Spinal cord

Spinal cord (medulla spinalis) is a set of nuclei of gray matter and white nerve fibers forming a pair of 31 segments. The spinal cord has a length of 43-45 cm and a mass of about 30-32, the composition of each segment includes the portion of spinal cord, corresponding sensor (sensitive) root entering the dorsal side, and the motor (motor) root, leaving the ventral surface of each segment. Dorsal the brain is located in the spinal canal, is surrounded by membranes, between which the cerebrospinal fluid circulates. At a length of the spinal cord occupies the space between I and the top cervical Read more [...]
