The nervous system is a complex network of nerves, the brain, and the spinal cord that sends messages between the brain and the body. The nervous system uses electrical and chemical signals to help the body's parts communicate with each other. The nervous system controls many aspects of health and well-being, including: Movement, Breathing, Vision, Thinking, Waking up, Emotions, Brain growth and development. The nervous system is made up of the central nervous system and the peripheral nervous system: Central nervous system: The brain and spinal cord Peripheral nervous system: All...

Muscles and glands are called effectors because they respond to the nervous system's directions. The basic unit of the nervous system is a nerve cell, or neuron. There are three broad functional classifications of nerves: Sensory (afferent), Intermediate, Motor (efferent). Show less
