Question

Quizplus · Accepted Answer

Ascending tracts carry sensory information towards the brain, while descending tracts carry motor information away from the brain. The dorsal root ganglion contains the cell bodies of sensory neurons, but it is not involved in transmitting information up the spinal cord to the brain. Afferent pathways also carry sensory information towards the brain, but this term is a broader concept and not specific to the spinal cord. Efferent pathways carry motor information away from the brain and are not involved in transmitting information up the spinal cord to the brain.
