In 2009, an SUV hit triathlete Lav Carson from backside spell he was out on a breeding rag. When Carson awoke in intensifier attention, doctors told him that he had ill discredited his cervical rachis and was a quadripeligic. “When I was a jr. guy, to me the opinion of existence paralytic, I was the kickoff someone to say I’d quite be deadened," Carson says. But inside a hebdomad, practically to the surprisal of his doctors, Carson began moving his workforce. Finally, afterward continued reclamation, he began to walkway. Carson, now 30, is what his spinal sawbones calls a “walk Read more [...]
Researchers suffer successfully repaired discredited spinal corduroys in mice, restoring the animals' power to hint in what could be a major find in the intervention of spinal corduroy injuries. According to a wallpaper promulgated yesterday in the daybook Nature, scientists from Pillowcase Westerly University in Cleveland were capable to successfuly fleck areas of discredited spinal corduroy. Old efforts to mending spinal corduroy weave birth proven inefficient. In the Cause Westerly cogitation, reserachers grafted cheek weave onto the department of discredited corduroy, so injected it with an Read more [...]
The biggest case of spinal injuries in the Joined States victimized to be car accidents, but a new cogitation conducted by Johns Hopkins University Cultivate of Medicament launch that for mass 65 and senior, nearly traumatic spinal injuries pass from dropping consume.What’s worsened, researchers establish that old adults with spinal corduroy injuries are fourfold more probably than jr. adults to die in the er from such an wound.The bailiwick, primitively promulgated in the Diary of Neurotrauma, analyzed 43,137 adults in infirmary exigency suite for spinal corduroy injuries Read more [...]
The following types of disorders are associated with sensitivity pathway lesions and spinal cord. When an abnormality at any level in one half of the spinal cord (compression of the tumor, hemorrhage or traumatic rupture) observed a peculiar pattern of the so-called Brown-Sequard syndrome (see Brown-Sequard syndrome), which falls on the affected side movement and proprioceptive (deep) the sensitivity of the site following spinal cord lesions, and on the opposite side of the body falls pain and temperature sensitivity. With the defeat of the two halves of the spinal cord, that is, the propagation Read more [...]
Sometimes used in spinal anesthesia. Needle is inserted in the back neural canal, passing between the last lumbar and first sacral vertebrae, or between I and II of caudal vertebrae (sacral epidural anesthesia). After the penetration of the needle into the spinal channel, as determined by the leakage of liquid droplets from the needle, remove 5 ml cerebrospinal fluid from the channel, which in return the same amount of 1% solution of novocaine.
Funicular myelosis (synonym: combined degeneration, combined sclerosis) - disease of the spinal cord that develops due to prolonged vitamin B12 deficiency and characterized by motor and sensory disorders. In most cases, funicular myelosis combined with pernicious anemia, at least - with other anemias, leukemias, Achille, stomach cancer, and sometimes develops after gastric resection or broad tapeworm infestations. When funikulyarnogo mieloza often affects both the side and rear columns of the spinal cord.
The disease usually occurs between the ages of 30-50 years. The patient complains of general Read more [...]
Complications. Blockade subarachnoid space with impaired patency of liquor ways adhesive process may be limited (most often in the lumbar region, at least in the big tank) and diffuse. Early symptoms of the blockade are radicular pain, mieliticheskie symptoms. When tsisternalnoy blockade appear forced position of the head, severe muscle tension neck syndrome, progressive hydrocephalus. Cerebrospinal fluid is characterized by inflammatory changes above the blockade and severe protein-cell dissociation from xanthosis below the blockade. Recently, under the influence of a more effective treatment Read more [...]
Trofonevrotichesky ossificans myositis (Myositis ossificans trophoneurotica; synonym: paraossalnoe ossification, paraartikulyarnoe ossification) - a type of heterotopic bone formation vneskeletnogo. Similar in morphology to the traumatic myositis ossificans. Result from alterations in motor and sensory innervation in injuries and diseases of the central and peripheral nervous system develops in the spinal cord after injury, fractures, bruises, compression, shock, and some diseases - cancer, myelitis, etc. It is observed in 20% cases of spinal cord lesions, often with concomitant damage to the Read more [...]
Tractotomy – An operation crossing pathways of the spinal cord or brain to stop conducting pathological impulses in upstream and downstream parts of the nervous system.
Tractotomy can be made at the level of the spinal cord (cordotomy), medulla (tabloid cordotomy, bulbar tractotomy), Midbrain (mesencephalic tractotomy), The brain (thalamocortical tractotomy).
The main indication for tractotomy are unquenchable pain syndromes that can not be conservative therapy and interventions in the peripheral nervous system.
Spondylitis - inflammation of the spine. Most often spondylitis (almost 95% of cases) has tubercular etiology, much less common staphylococcal, syphilitic, posletifozny spondylitis, actinomycosis of the spine, chronic osteomyelitis of the vertebrae.
Fig.1. The destruction of the vertebrae in tuberculous spondylitis.
Trachelokyphosis occurs mainly in children and frequency is one of the highest among all forms of osteoarticular tuberculosis (see). Currently, due to the broad holding absolute control activities - the number of patients with tuberculous spondylitis is not great. Tuberculous Read more [...]
Cerebrospinal anesthesia (Synonym: spinal, A., A. lumbar). Anesthetics injected into the subarachnoid space, and the violation of the conduction of the nerve roots are lost in the beginning of pain, and then the temperature and tactile sensitivity. Simultaneous anesthesia sympathetic fibers leads to paralysis and expansion vasomotors arterioles in the anesthetized area, which leads to lower blood pressure.
Indications: spinal anesthesia can be used for most surgical procedures on organs located below the diaphragm, it is especially indicated for major surgery in the abdominal cavity, which is Read more [...]
At the segment level spinal cord closed arc of unconditioned reflexes. For example, a hammer blow on the tendon below the kneecap tendon irritation receptors, further nerve pulse by dorsal root reaches the posterior horn cells, and then transferred to the motor cells of the anterior horn and in the form of motor pulse anterior roots and motor fibers are sent to the muscle, causing it to decrease, causing extension of the lower leg. Knee-jerk reflex arc passes through II - IV lumbar segments of the spinal cord, the Achilles reflex arc-through I-II sacral segments. Reflex with biceps tendon passes Read more [...]
Thus, the signaling activity of the cerebral hemispheres of the human body makes it possible to more finely and accurately respond to stimulation of the environment.
Opening Pavlov essence and value of the second system was proof that man - A social being, and the second signal system is a "regulator of human behavior." Correct integration of the first and second signaling systems provides a person of normal relations with the world.
What should be the perfect structure of the whole nervous system, if it is there are such complex processes!
The brain is closely connected with the life Read more [...]
Injury spinal cord include bruises, overdistension, tears and a complete break substance spinal cord and its membranes. These injuries occur in wrestling, gymnastics, acrobatics, diving and skiing and other sports. Often these injuries combined with vertebral fractures and dislocations.
The mechanisms of these injuries include: hyperextension spinal cord with excessive bending or straightening of the cervical spine, compression spinal cord fractures and dislocations of the cervical, thoracic or lumbar spine, damage to the brain and its membranes by shocks.
Contusion of the spinal cord can occur Read more [...]
Spinal injuries - one of the most severe injuries of the musculoskeletal system. This is due to the variety of functions the spine: first, ensuring the normal function of complex neural connections carried the spinal cord and its elements, and secondly, the spine - an important link musculoskeletal man carrying a large static and dynamic loads.
According to the 3. V. Basilevsky, Priorov and other spinal injury ranged from 2 to 18%, remains high, and mortality. With injuries of the cervical spine, it is 33.3%, breast - 8.3%, lumbar - 6.2% (VV Gorinevskaya, 1958).
Of spinal injuries are four common Read more [...]
g) "dislocations of the cervical vertebrae."
This also should be classified and subluxations of the cervical vertebrae, if they were accompanied by life-threatening symptoms;
h) "closed spinal cord injury in the neck."
This refers to the violation of the integrity of the spinal cord hemorrhage in its substance or a shell in the neck due to injury;
i) "perelomovyvih fracture or one or more of the thoracic or lumbar spine with spinal cord dysfunction, or the presence of clinical judgment of severe shock."
These injuries can be life-threatening only if they are accompanied Read more [...]
Spinal cord - Part of the central nervous system, located in the spinal canal. Conventional boundary between the medulla oblongata and spinal cord chiasm is the place of origin of the pyramidal tract and the first cervical spine.
Spinal cord as well as the head, covered with meninges (see).
Anatomy (structure). Dlinniku on spinal brain is divided into 5 parts, or parts: cervical, thoracic, lumbar, sacral and coccygeal. Dorsal brain has two bulges: Shane associated with innervation of hands and lumbar associated with innervation of the legs.

Amyelotrophy (Synonym: tabes dorsalis, progressive locomotor ataxia, tabes spinal cord) - late form of neurosyphilis. Dorsal tabes develops after several, sometimes many years after the infection of syphilis in untreated or inadequately treated syphilis. Histologically determined degenerative phenomena and dorsal root fibers atrophy and posterior columns of spinal cord. Early symptoms dorsal tabes are sharp shooting pain and paresthesia (see sensitivity), there is numbness in the legs, a feeling of pins and needles, etc. Pain usually do not have a specific location, are found in different Read more [...]
Syphilitic meningitis more likely to develop in the second stage of syphilis and occurs in the form of latent or acute meningitis, which is characterized by high fever with pronounced meningeal symptoms. Of cerebrospinal meningitis different nature of changes in cerebrospinal fluid and positive serological reactions. In more recent cases of syphilis may be a gummy syphilitic meningitis, characterized by sluggish, with exacerbation, lesions of the cranial nerves, a little severe meningeal syndrome, but with positive serological reactions of the spinal fluid. Syphilitic meningitis specific treatment Read more [...]
Sensitive part of the pulses coming from the genital organs, forms the spinal reflex arc that operates automatically. Remaining sensitive impulses are sent to higher centers. Spinal centers of erection and ejaculation are less differentiated than the higher centers, so they function according to the type of spinal automatism and often subjected to functional disorders.
The mechanism of the nervous regulation sexual function based on a system of the above centers in order of subordination of the different levels of the central nervous system. The strength and intensity of sexual desire, erection, Read more [...]
