Question

What happens when the spinal cord is injured

A) the parts of the body using the damaged areas lose sensation
B) The effected neurons in the CNS regenerate gradually.
C) The path of impulses in the nervous system may be disrupted.
D) Both (A) and (B)

Answer 1

A and B. When a person injures their spine, body movements and neurons can become affected. The CNS or central nervous system is what controls all this.

Answer 2

The answer is c)The path of impulses in the nervous system may be disrupted

Step-by-step explanation:

A spinal cord injury causes apoptosis of the oligodendrocytes found on damaged areas of the cord, several days or weeks later. The death of these oligodendrocytes is another serious consequence of the lesion, since these cells are what make up myelin, which is the one that envelops the axons, accelerating the direction of nerve impulses. This apoptosis causes axons that are still intact to lose myelin, which incapacitates the spinal cord to communicate with the brain.
