Structure of Neurons

Cell Body - contains nucleus and organelles

Dendrites - receive input

Axon - conducts impulses away from the cell body

Axon hillock - an enlarged region where an axon attaches to the cell body

Synaptic terminal - Neurotransmitters are manufactured in the cell body but released from synaptic terminals. The neurotransmitters stimulate other neurons.

Synapse - A synapse is the junction between the synaptic terminal and another cell. The other cell is called a postsynaptic cell.
