Short Essay on “Spinal Cord”

The spinal cord is an important structure of the central nervous system. It is an extension of the brain, it is a rough cylindrical shape and there are two long feeling structures in the skeleton

The spinal cord starts from the brainstem, extends to the backbone, and ends with the buttocks. Appearance, interior is gray, outside is white

The spinal cord is protected by 24 spinal vertebrae from the cervical, thoracic, lumbar, humeral and caudal vertebrae.

The internal structure of the spinal cord is simpler and more uniform in its various parts than the brain. Even if you cut (cut) anywhere, it shows the same essential appearance. Since the interior is gray matter (cell body), its distribution is 10 in order to represent the butterfly image, the basic shape is the letter H, the outer gray matter is a large white column, and various fiber bundles up and down Construct a rope to be transmitted. Splitting the wire into two symmetrical halves is two intermediate cracks, dorsal and ventral cracks. Between them there are two committees in the middle of the rope that connect the two parts of the rope.

Sensory nerves enter the spinal cord by heat, colds, pain, stress and muscle activity

It is responsible for the action known as reflex action. Reflex action is an automatic, unwilling reaction caused by stimulation. It mediates complicated reflexive behaviors such as blinking, subconsciousness, sneezing, coughing. Spinal cord injury leads to paralysis

Spinal cord injury is caused by spinal cord injury and causes complete or incomplete paralysis. Complete spinal cord injury means that the spinal cord is completely severed and people can no longer walk. Incomplete spinal cord injury means that the spinal cord is still intact but does not cross the spinal cord due to trauma from foreign body or bone. The degree of spinal cord injury is incomplete. I saw an example of a sliding disk in this figure. The sliding plate, in most cases, can cause severe pain, even sometimes even pain, and can be treated with analgesics, rest or surgery. It is definitely not a mild disorder, but as the spinal cord remains intact, the severity of the intervertebral disc slide is not so high that there is no damage to the nerve. However, more serious consequences occur when the spinal cord is damaged or damaged.

Spinal cord injury (SCI) is classified as a spinal cord injury and causes temporary or permanent changes in normal spinal movement, sensory or autonomic function, spinal cord injury, spinal cord or nerve damage at the end of the spinal canal. Power, sensation, and other physical functions achieve a permanent change. It is not necessary to cut the spinal cord due to loss of function. Symptoms vary greatly from pain to paralysis, incontinence, where spinal cord and nerve roots are damaged.
