Both the brain and spinal cord receive signals from the afferent neurons and send signals to muscles and glands through efferent neurons.
How does the nervous system control and coordinate the functions throughout the human body?
At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body. It does this by extracting information from the environment using sensory receptors. This sensory input is sent to the central nervous system, which determines an appropriate response.
