The two functional divisions of the peripheral nervous system are the afferent and efferent divisions . What are their respective functions? 1. Control of the central nervous system/control of the peripheral nervous system 2. Control of neurons/control of neuroglia 3. Sensory input to the CNS/carries motor commands to muscles or glands 4. Carries motor commands to muscles or glands/sensory input to the CNS
