Quizplus · Accepted Answer

The posterior (dorsal) root carries sensory information only, as it contains the sensory neurons that transmit information from the periphery to the spinal cord. The anterior root carries motor information only, as it contains the motor neurons that transmit information from the spinal cord to the muscles and glands. The posterior ramus and anterior ramus each contain both sensory and motor fibers, as they are branches of the spinal nerve that innervate different regions of the body.
