Document Summary

The nervous system: network of neurons, neurons. Cells that receive, integrate, and selectively transmit information: central nervous system (cns) Brain and spinal cord: peripheral nervous system (pns) Detect information from the physical world and pass that information to the brain.

Direct muscles to contract or relax, thereby producing movement. Movements that do not communicate with the brain. Receive signals from other neurons: cell body, axon. Carries action potentials away from cell body to terminal buttons: myelin sheath. Fatty insulation on axon helps action potentials move down axon: terminal buttons. Ends of axon where neurotransmitters are housed: synapse.
