Consist of:
•Cell body (soma, Perikaryon)
–Contains the nucleus and most of the cell's organelles
–Nissl bodies (RER)
•Dendrites
–Processes that branch off the cell body and receive input from other neurons at specialized junctions called synapses
•Axons (nerve fiber)
–Processes that send information in the form of action potentials (AP)
–only one axon comes off the cell body at the axon hillock
–may have branches called collaterals
–axon terminal where the neuron synapses with another neuron or effector organ.
