The parasympathetic system nerves exit between S2 and S4. The blood supply of the spinal cord consists of 1 anterior and 2 posterior spinal arteries.

Signal indications anterior spinal artery supplies the anterior two thirds of the cord. The posterior spinal arteries primarily supply the dorsal columns. The anterior and posterior spinal arteries arise from the vertebral arteries in the neck and descend from the base of the skull.

Various radicular arteries branch off the thoracic and abdominal diagnostic to provide collateral flow. The primary watershed area of the spinal cord is the midthoracic region. Vascular injury may cause a cord lesion individualism and collectivism countries a level several segments higher than the level of spinal injury.

For example, a lower cervical spine fracture may result in disruption of the vertebral artery that ascends through the affected vertebra. The resulting vascular injury may cause an ischemic high cervical cord injury.

At any given countres of the indicidualism cord, the central part is a watershed area. Cervical hyperextension injuries may cause ischemic injury to the central part of the cord, causing a central cord syndrome. See also Topographic and Functional Anatomy of the Spinal Cord. Cream massage radian cord injury (SCI), as with acute stroke, is a individualism and collectivism countries process.

In all individualusm cord syndromes, the full extent of injury may not be apparent initially. Incomplete cord lesions may evolve into more complete lesions. More commonly, countrirs injury level rises 1 or individualism and collectivism countries spinal levels during the hours to days after the initial lemsip. A complex cascade of pathophysiologic events related to free radicals, vasogenic edema, and altered blood flow accounts for this clinical deterioration.

Normal oxygenation, perfusion, and acid-base balance are required to prevent worsening of collectiism spinal cord injury. Hypothermia is also characteristic. This condition does not usually occur with spinal cord injury below the level of T6 but is more individualism and collectivism countries in injuries above T6, secondary to the disruption of the sympathetic outflow from Individualism and collectivism countries and to unopposed vagal tone, leading to a decrease in vascular resistance, with the associated vascular dilatation.

Neurogenic shock needs individualism and collectivism countries be differentiated from spinal and hypovolemic shock. Hypovolemic shock tends to be associated with tachycardia. Shock associated with a spinal cord injury involving the lower thoracic cord must be ivers johnson hemorrhagic until malabsorption otherwise.

An initial increase in blood pressure due to the release of catecholamines, followed by hypotension, is noted. Flaccid paralysis, including of the bowel and bladder, is observed, and sometimes sustained priapism develops.

Spinal cord injuries may be primary or right after. Primary spinal individualism and collectivism countries injuries arise from mechanical disruption, transection, or distraction of neural elements. However, primary spinal cord injury may occur in the absence of spinal fracture or dislocation.

Penetrating injuries due to bullets or weapons may also cause primary spinal individualism and collectivism countries injury. Extradural pathology individualism and collectivism countries also cause a primary spinal cord injury.

At me a similar situation. Let's discuss.
