The peripheral unquiet constitution consists of sensory neurons streak from stimulus receptors that inform the telephone trade Nervous ashes of the stimuli. It as well consists of force backward neurons running from the primordial Nervous System to the muscles and glands, called effectors, which take up action. The peripheral head-in-the-clouds system is further subdivided into an sensory region and an move naval air division. The sensory division transmits impulses from peripheral organs to the Central Nervous System. The motor division transmits impulses from the Central Nervous System out to the peripheral organs to cause an effect or action. The Somatic flyaway system of the motor division supplies motor impulses to the haggard muscles.

Because these nerves give up conscious control of the osseous muscles, it is sometimes called the voluntary nervous system. The autonomic nervous system supplies motor impulses to cardiac muscle, to fluent muscle, and to glandular epithelium. Because the autonomic nervous system regulates involuntary or automatic functions, it is called the involuntary nervous system. The brain is the source of all our behavior, thoughts, feelings, and experiences. In humans, the brain weighs meagrely 3 pounds.
