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: -Sensory neurons carry nerve impulses from sense organs and internal organs to the central nervous system. Motor neurons carry nerve impulses from the central nervous system to organs, glands, and muscles-the opposite direction.
Detailed explanation-3: -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-4: -A sensory neuron transmits impulses from a receptor, such as those in the eye or ear, to a more central location in the nervous system, such as the spinal cord or brain.
Detailed explanation-5: -The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS.
