Explanation:
Detailed explanation-1: -Afferent, or sensory, neurons carry impulses from peripheral sense receptors to the CNS. They usually have long dendrites and relatively short axons. 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-2: -A stimulus causes an impulse to be generated in a sensory neurone that is transmitted to the CNS, where it stimulates an impulse in a relay neurone. This connects to a motor neurone so that an impulse passes to an effector.
