Nervous System: Brain: Nerves (neurons): Spinal Cord: Autonomic: Somatic:

Functions of the Nervous System 1)Receives Information 2)Responds to Information

The Nervous System The control center for the entire body. Made up of brain, spinal cord, and neurons.

Brain Coordinates actions and reactions

Nerves/Neurons Cells that carry messages back and forth from the brain.

Spinal Cord A group of neurons along the spine that carries information from the brain to the rest of the body.

Autonomic When your nervous system works automatically, like when your heart beats.

Somatic When you tell your body what to do (voluntary), like petting a cat.

Nervous System Diagrams p 54 Nervous System Diagram Label Brain, Spinal Cord, Nerves Autonomic Nervous System Draw three examples of human body functions controlled by the autonomic nervous system. Somatic Nervous System Draw three examples of human body functions controlled by the somatic nervous system. Don’t Touch That Cactus! Draw someone touching a cactus, and the path of the impulse as it travels through the nervous system.
