Detailed explanation-1: -The word ‘aferent’ means “steering or conducting something towards a destination”. The afferent nerves are the messenger neurons that bring the information from different parts of the body to the central nervous system (CNS).
Detailed explanation-2: -The afferent or sensory division transmits impulses from peripheral organs to the CNS. The efferent or motor division transmits impulses from the CNS out to the peripheral organs to cause an effect or action.
Detailed explanation-3: -Efferent neurons – also called motor neurons – are the nerves responsible for carrying signals away from the central nervous system in order to initiate an action. When sensory input is brought to the brain, it sends signals for a motor response to your muscles and glands via the efferent neurons.
