What are the main parts of the nervous system and their functions?
The Brain and Spinal Cord Are the Central Nervous System. Nerves and Sensory Organs Make Up the Peripheral Nervous System. Together, the central nervous system (CNS) and the peripheral nervous systems (PNS) transmit and process sensory information and coordinate bodily functions.
What are the two divisions of the autonomic nervous system?
The autonomic nervous system comprises two antagonistic sets of nerves, the sympathetic and parasympathetic nervous systems. The sympathetic nervous system connects the internal organs to the brain by spinal nerves.
