Question

select the correct answer.
what could be a result of an injury to the dorsal column?
a. loss of sensation to pressure and touch
b. loss of control over all involuntary movements
c. inability of the body to maintain homeostasis
d. inability to regulate the sleep-wake cycle
e. loss of motor control

Explanation:

The dorsal column of the spinal cord is responsible for transmitting sensory information like pressure and touch. Option A relates to loss of such sensations. Option B is incorrect as involuntary movements are controlled by other systems. Option C is about homeostasis, not dorsal column. Option D involves sleep - wake cycle regulation (related to the brain, not dorsal column). Option E is motor control, which is handled by motor pathways, not the dorsal column (sensory).

Answer:

A. loss of sensation to pressure and touch
