Detailed explanation-1: -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-2: -The visceral motor division, also known as the autonomic nervous system, carries signals to glands, cardiac muscle, and smooth muscle. It can be further divided into the sympathetic and parasympathetic divisions. The sympathetic division tends to arouse the body to action.
Detailed explanation-3: -Afferent or sensory neurons collect stimuli received by receptors throughout the body, including the skin, eyes, ears, nose, tongue as well as pain and other receptors in the internal organs. Sensory information is transmitted to the central nervous system, which includes the brain and spinal cord.
