  Spinal cord - Wikipedia, the free encyclopedia
The spinal cord is a part of the vertebrate central nervous system that is enclosed in and protected by the vertebral column (it passes through the spinal canal).
Spinal cord injuries are caused by damage to the spinal cord, such as falling on the neck or back, or having the spinal cord moved or disrupted in another way.
The spinal cord originates inside the brain at the inferior end of the medulla oblongata, exiting the skull via the foramen magnum.

The violent shaking of the spinal cord and the spinal nerves in a serious accident may, however, be followed by some functional disturbance, which may be associated with pains in the back, by numbness and tingling in the limbs, or with muscular weakness.
Spinal induction obviously tends to connect to this extensor-thrust flexion of the limb as an aftereffect.
The spinal cord is not only the seat o~f reflexes whose centres lie wholly within the cord itself; it supplies also conducting paths for nervous reactions initiated by impulses derived from afferent spinal nerve, but involving mechanisms situate altogether headward of the cord, that is to say, in the brain.

 Spinal Cord - MSN Encarta
The cord, like the brain, is encased in a triple sheath of membranes and is partially divided into two lateral halves by a median fissure toward the front and a median partition toward the rear; 31 pairs of spinal nerves arise, each by an anterior and a posterior root, from each side of the cord.
The spinal cord functions in the transmission of ascending impulses to the brain and of descending impulses from the brain to the cord.
The spinal cord relays impulses also to the muscles, blood vessels, and glands by means of outgoing nerves, either in response to incoming stimuli or to signals from higher levels.

spinal cord, the part of the nervous system occupying the hollow interior (vertebral canal) of the series of vertebrae that form the spinal column, technically known as the vertebral column.
Three protective membranes, the meninges, wrap the spinal cord and cover the brain : the pia mater is the innermost layer, the arachnoid lies in the middle, and the dura mater is the outside layer, to which the spinal nerves are attached.
The spinal cord mediates the reflex responses to some sensory impulses directly, i.e., without recourse to the brain, as when a person's leg is tapped producing the knee jerk reflex.

 MedlinePlus Medical Encyclopedia: Spinal cord trauma
Spinal cord trauma is damage to the spinal cord that results from direct injury to the cord itself, or from indirect injury from damage to the bones, soft tissues, and blood vessels surrounding the spinal cord.
Spinal cord injuries occur in approximately 12,000-15,000 people per year in the U.S. About 10,000 of these people are permanently paralyzed, and many of the rest die as a result of their injuries.
If spinal cord compression is caused by a mass (such as a hematoma or bony fragment) that can be removed or brought down before there is total destruction of the nerves of the spine, paralysis may in some cases be reduced or relieved.

 Spinal cord
The cord is surrounded by the meninges: The tough dura with subjacent arachnoid are separated from the cord by the subarachnoid space.
Note that a classic (but uncommon) sign of intrinsic cord lesions is "sacral sparing": this is because the sacral segments of the spinothalamic tract are closest to the outside of the cord and therefore are not affected until late by a gradually increasing central cord lesion.
Commonest causes of a spinal cord lesion with a normal myelogram or MRI are syphilis and transverse myelitis.

The spinal cord has many nerve fibers that serve as the messenger system for the human body, delivering commands from the brain to different parts of the body.
The spinal cord (and therefore the series of nerves that comprise the spinal cord) travel through the spinal column, which is divided into four sections: the cervical region, or neck area; the thoracic area, or midsection of the spine; the lumbar area, or lower back, and; the sacral area, or tailbone.
Quadriplegia (also known as Tetraplegia) generally describes the condition of a person with a spinal cord injury that is at a level from C1 to T1.

 eMedicine - Spinal Cord Infections : Article by Andrew K Chang, MD
Background: Infections involving the spinal canal include epidural abscesses (infection in the epidural space), meningitis (infection of the meninges), subdural abscesses (infections of the subdural space), and intramedullary abscesses (infections within the spinal cord).
In children, intramedullary abscess of the spinal cord is predominantly secondary to direct contiguous spread of infection from the skin.
Spinal dermal sinuses, seen in association with the abscesses, result from defective separation of the epithelium ectoderm from the neural ectoderm and subsequent communication between the skin and deeper structures.

 SPINAL MOTOR STRUCTURES
Although we usually study the spinal cord as a series of cross sections, it is important to remember that it is in fact a column, with continuous tracts and cell columns.
However, the cord can be divided into segments by the nerve roots that come off of it; although the rootlets branch off nearly continuously, they coalesce into about 31 discrete nerves along the cord (8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal nerves).
All of the spinal reflexes are local - all of the cells involved are contained within one or two segments, and cortex is not necessary.

Anatomically, neoplasms of the spinal cord may be classified according to the compartment of origin, either intramedullary (inside the cord) or extramedullary (outside the cord).
Although metastatic lesions are not primary neoplasms arising from neural elements of the spinal cord, they are featured in this discussion because metastases cause 85% of the cases of spinal cord compression, and the clinical presentation tends to be indistinguishable from that of primary cancers of the spinal cord.
Metastases to the substance of the cord (intramedullary) are relatively rare.
