Question

Transection of C4 and above on the spinal cord often results in:

a. Paraplegia

b. Quadriplegia

c. Hemiplegia

d. Monoplegia

Answer 1

A transection of the spinal cord at C4 and above leads to quadriplegia, resulting in paralysis of the arms, legs, trunk, and pelvic organs.

Step-by-step explanation:

Transection of the spinal cord at C4 and above often results in quadriplegia, which means that the paralysis affects the arms, hands, trunk, legs, and pelvic organs. The spinal cord is the main pathway for information connecting the brain and the body, and an injury at the C4 level interrupts signals to and from the brain to all areas below the neck. Paralysis after such an injury is profound because the injury occurs high on the spinal column, impacting a larger portion of the body.
