In brief: Nerves and more

The nervous system is composed of the brain, spinal cord, peripheral nerves, and the organs supplied by those nerves.
Peripheral nerves supply sensation and muscle control. Splanchnic nerves control intestinal function. Sympathetic and parasympathetic nerves control blood flow, sweat, and other functions.
