Typical neuron with labels showing dendrites, cell body, hillock, axon, and presynaptic terminal

Typical neuron (green)

Dendritic spines are present on some dendrites. Dendrites project from the cell body in a tree-like fashion.

Dendrites and spines

The neuronal cell body has organelles similar to other cell types.

Cell body and organelles

Axon diameter and amount of myelin can vary among neurons.

Axon diameter

The presynaptic terminal contacts a postsynaptic cell at the synapse.

Presynaptic terminal

The axon is a long process that begins at the cell body at a region called the axon hillock and ends at the presynaptic terminal.

Axon and axon hillock

Myelin covers the axon and speed up action potential propagation. The space between myelin is called the Nodes of Ranvier.
