Question 4 • Biology - SC3209 IC

Why might damage to the nervous tissue in the spinal cord lead to paralysis?

Answer
A
Damage results in the loss of signals to muscles that produce movement.
B
Damage results in the inability of the body to differentiate between voluntary and involuntary movement.
C
Damage results in the inability of the body to produce connective tissue to support movement.
D
Damage results in the decreased production of actin and myosin for contraction.

Explanation

The spinal cord carries nerve signals between the brain and the muscles. Damage to its nervous tissue can interrupt signals that tell muscles to move, causing paralysis. Therefore, choice A, “Damage results in the loss of signals to muscles that produce movement,” is correct.
