Quizplus · Accepted Answer

The dorsal root ganglion of a spinal nerve contains the cell bodies of sensory neurons, which transmit information from sensory receptors (such as those in the skin or muscles) to the spinal cord. The gray matter of the spinal cord contains the cell bodies of motor neurons, which transmit information from the spinal cord to muscles or glands, as well as the cell bodies of association neurons (also known as interneurons), which connect sensory and motor neurons and allow for complex processing of information within the spinal cord. Therefore, option D (sensory/motor) is the best choice.
