Dendrites

Cell Body (Soma)

Contains the nucleus and other parts of the cell needed to sustain its life.

Myelin Sheath

A fatty covering around the axon of some neurons that speeds neural impulses.

Neurotransmitters

Chemicals contained in terminal buttons that enable neurons to communicate. Neurotransmitters fit into the receptor sites on the dendrites of neurons like a key fits into a lock.

Dendrite

Rootlike parts of the cell that stretch out from the cell body. Dendrites grow to make synaptic connections with other neurons.

Synapse

The space between the terminal buttons of one neuron and the dendrites of the next neuron.

Axon

Wirelike structure ending in the terminal buttons that extends from the cell body.

Terminal Buttons

the branched endow the axon that contains neurotransmitters.
