If the spinal cord is severely injured, what may happen to reflex actions?

Answer and explanation

Correct answer: They may be affected or weakened

The governing concept is the role of the spinal cord in reflex pathways. Many reflexes are coordinated through the spinal cord, which receives sensory information and sends motor instructions to an effector. Severe injury can interrupt or impair these nerve pathways, so the reflex response may become weak, delayed, abnormal, or absent. Therefore option B is the appropriate general answer; the other choices are biologically unrelated.
