Document Summary

Coordinated activities of the entire body using neurons. Functions: monitor internal and external environment. Integrate sensory information: coordinate voluntary and involuntary responses, maintain homeostasis. Neurons: cells that carry information or nerve impulses, sensory neurons. Carry information from environment to central nervous system (cns: motor neurons. From cns to effector cells: association neurons/interneurons. Pure electricity triggered by opening or closing: action potentials. A shift in vm towards more positive charge (>-70: repolarize. A shift in vm towards a more negative charge (
