Question

Quizplus · Accepted Answer

Information from sensory receptors travels up the spinal cord to the brain via the ascending tracts, while motor information travels down the spinal cord via the descending tracts. The ventral root ganglion is involved in the transmission of motor information out from the spinal cord, and efferent pathways are involved in the transmission of motor information to the muscles and glands. So, the correct choice is C, via ascending tracts.
