Document Summary

Central command system which controls thought and movement. Functions: receiving, processing, & storing incoming info; sending out messages to muscles, glands, & internal organs. Peripheral nervous system: connects cns to sensory organs. Somatic nervous system: sensory nerves send info from skin/muscles to cns about pain/temperature and informs muscles when to act. Neurons: individual cells which receive, integrate, and transmit info. Sensory/afferent neurons: carry info to the brain. Motor/efferent neurons: carry brain"s output to muscles/glands/organs. Mirror neurons: activated by performing an action or by seeing another perform the same action. Glial cells: non-neuron cells that provide a supportive function to hold in place/nourish/insulate neuron. Dendrites: receive messages from other neurons, transmit to cell body. Cell body/soma: keep neurons alive; contains substances for growth, determines whether to fire. Axons: transmit messages away from cell body to other neurons/muscles/glands. Myelin sheath: fatty coating on axon which helps nerve impulse travel faster. Synapses: gaps between neurons: presynaptic-send info; postsynaptic receive info.
