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 central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).
Detailed explanation-3: -Yes, the afferent nerves are the sensory nerves that carry sensory impulses from the different organs to the CNS.
Detailed explanation-4: -Efferent neurons have long axons and short dendrites. Afferent neurons originate from cell bodies outside the CNS. Conversely, efferent neurons cell bodies are within the CNS.
