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

A.  loss of sensation to pressure and touch

Explanation:

Posterior column-medial lemniscus pathway  also known as  the dorsal column–medial lemniscus pathway (DMLP) is a pathway involved in recognition of sensory simulations and is found in central nervous system.

It is involved in conveying  different sensations like like touch and vibration from skin and joints. Therefore, it can be said that the pathway plays significant role in perception of sensory information from different parts of the body. If any damage occurs to the pathway it can  result in loss of sense of touch and vibration which is ultimately a lack of ability of a person to sense a touch or pressure in the body.

Hope it helps!
