Question

Quizplus · Accepted Answer

The dorsal and ventral roots on each side of the spinal cord carry different types of nerve fibers. The dorsal roots carry afferent sensory fibers that transmit sensory information from the periphery to the spinal cord, while the ventral roots carry efferent motor fibers that carry motor signals from the spinal cord to the periphery. If both the ipsilateral dorsal and ventral roots were cut (i.e. on the same side of the spinal cord), both the sensory and motor fibers would be severed, resulting in a loss of both sensation and motor control on that side of the body. Therefore, choice D is correct. The other options are incorrect because they either overgeneralize or only account for half of the nerve fibers that would be affected.
