• Consists of of our Nerves (bundles of axons into electrical cables) located outside of the brain and spinal cord
• *Sensory and Motor Neurons*

• Coordinates body movements

• Regulates activities under conscious control
• Control system of the body
• Glands, and the muscles of our organs

• System of glands that release hormones into the bloodstream that regulate the body and mind
• Influences mood, growth, metabolism, sex drive, etc.

• Consists of the brain and spinal cord
• Brain

• Spinal cord
– Information highway that connects the peripheral nervous system to the brain
• Sensory info goes up, motor control goes down
