What organs are included in the nervous system and how do they work together to regulate and coordinate the body's functions?

The organs in the nervous system include the brain, spinal cord, and nerves. These organs work together to regulate and coordinate the body's functions by sending and receiving electrical signals that control movement, sensation, and other bodily processes. The brain processes information from the senses and sends out instructions to the rest of the body through the spinal cord and nerves, allowing for communication and coordination of various functions.
