Detailed explanation-1: -The motor (efferent) division carries motor signals by way of efferent nerve fibers from the CNS to effectors (mainly glands and muscles).
Detailed explanation-2: -The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS.
Detailed explanation-3: -Afferent neurons carry information from the CNS to the effector organs and tissues. Ganglia are the bulges near the spinal cord, where the cell bodies of afferent neurons reside.
Detailed explanation-4: -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.
