Detailed explanation-1: -Efferent neurons, also called motor neurons, are the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system in order to initiate an action. In other words, they are the neurons that tell your body to perform an action, such as removing your hand from a hot pan.
Detailed explanation-2: -There are three types of efferent fibers: general somatic efferent fibers (GSE), general visceral efferent fibers (GVE) and special visceral efferent fibers (SVE).
Detailed explanation-3: -Afferent neurons are sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain, while efferent neurons are motor neurons that carry neural impulses away from the central nervous systme and towards muscles to cause movement.
Detailed explanation-4: -The afferent neurons are also known as the sensory neurons. They bring the stimuli from the sensors (e.g., skin, eyes, ears) to the CNS. The efferent neurons are also known as motor neurons. They bring the responses from the brain to the muscles and the glands.
Detailed explanation-5: -All motor neurons are efferent neurons as these neurons send signals from the central nervous system to effector organs like muscles or glands for responding to the stimulus and perform their function.
