Detailed explanation-1: -Motor or efferent neurons transmit impulses from the central nervous system towards the effectors (muscle or glands), while sensory neurons transmit impulses from the sense organs towards the central nervous system (brain and spinal cord).
Detailed explanation-2: -Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands. Efferent neurons usually have short dendrites and long axons.
Detailed explanation-3: -For motor responses to be initiated, it requires sensory input to the brain. Various sensory information is relayed through the brainstem. Such tracts include: The dorsal column-medial lemniscus pathway, which relays sensory information related to fine touch, vibration sensation, and proprioception.
