cell body (soma), 5 um-150um spherical, pyramidal fusiform stellate in shape, Processes (neurites) dendrites: like branches of tree axon: long thin cord-liked process Structure of neurons: morphology
Terminal branches of axon (form junctions with other cells) Dendrites (receive messages from other cells Axon (passes messages away from the cell body to Cell body other neurons ( the cell's life. muscles, or glands) support center Myelin sheath (covers the axon of some rons and helps speed Neural impulse neural impulses (electrical signal traveling down the axon
Structure of neurons the soma Cell membrane unit membrane-excitability, to receive stimuli initiate and conduct nerve impulse membrane proteins- rich in ion channels and receptors
Cell membrane • unit membrane-excitability, to receive stimuli, initiate and conduct nerve impulse • membrane proteins- rich in ion channels and receptors Structure of neurons-the soma
