Detailed explanation-1: -Sensory neurons carry impulses from the receptors in the sense organs to the CNS, while the association or connection neurons carry impulses from the sensory to the motor neurons. The motor neurons carry impulses from the CNS to the effectors.
Detailed explanation-2: -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.
Detailed explanation-3: -A motor neuron is a nerve cell that transmits impulses from the brain or spinal cord to a muscle or gland.
Detailed explanation-4: -The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS.
Detailed explanation-5: -The peripheral nervous system (PNS), which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons. Sensory neurons bring signals into the CNS, and motor neurons carry signals out of the CNS.
