Quizplus · Accepted Answer

Ascending tracts are nerve pathways that transmit sensory information from the peripheral nervous system to the CNS. They carry signals derived from afferent input up the spinal cord to the brain, allowing for sensory perception and interpretation. Thus, option D, "They transmit signals derived from afferent input up the spinal cord to the brain" is the correct answer.
