Document Summary

Brain (interprets and stores informaion, sends orders to muscles, glands to organs) Spinal cord (communicate with all the sensory muscles and organs, connect brains to. Includes cranial nerves and spinal nerves (body cns: transmit sensory informaion) (cns body: transmit motor/commands) Skeletal nervous system/somaic (carries informaion & controls muscle movement: sensory or aferent, motor or eferent. Gila: supporing cells, help funcioning & protecion of neurons. Paricipate in brain communicaions: most abundant & versaile gila: astocytes. Cell body: contain structures that maintain cell health and metabolism: nucleus: contains genes that make the proteins that run the cell. Axon: transmit informaion from the neuron, nerve ibre: myelin: covering that makes the axon faster and more eicient. Synapse: gap between 2 neurons: nerve-bundle of axon ibres, each axon is an extension of the cell body, nerves transmit informaion within the pns, between pns and cns. Tracts: nerves that are within the brain and spinal cord.
