Nettet30. nov. 2024 · Spinal cord: Cross-section. Descending tracts are the pathways by which motor signals are sent from the brain to the spinal cord. They are also called motor tracts, due to their involvement in movement coordination. These tracts can be classified by their structural arrangement, into lateral and medial tracts. NettetTerms in this set (57) What are the three general classes of neurons that correspond to the three major aspects of nervous system function? - Motor neurons that send signals predominantly to muscle and gland cells. - interneurons that lie between, and interconnect the incoming sensory pathways and the outgoing motor pathways of the CNS.
