Functions of spinal cord

A huge number of neural circuits close in the spinal cord through which the movement of skeletal muscle (somatic reflexes) and the activities of the internal organs (autonomic or visceral reflexes) are regulated. There are centers of tendon reflexes and reflexes that regulate the tone (tension) of skeletal muscles and posture, activity of the stomach and intestines, blood vessels, bladder, heart muscle, and so on. Usually, the spinal cord reflexes are conducted under the supervision of the nerve centers, placed in the brain. At the same time the supreme centers of the somatic reflexes regulation are found in the cerebral cortex, and the person can arbitrarily control their expression. Supreme centers that serve visceral reflexes are placed in the brain stem and midbrain. Therefore, the influence on the internal organs activity is not controlled by consciousness, and made involuntarily (stand-alone). Taken from http://worldofschool.org

Due to injuries of the spinal cord, its pathways may break. This is followed by partial or complete loss of sensation and the inability of man to perform voluntary movements.

The spinal cord injury in the site of cervical vertebrae is especially dangerous.
