Nerve cell and synapses. Artwork of a nerve cell (neurone) of the brain with a close-up of a synapse. The nerve cell body is at lower right. It has a central nucleus (circle) and axons and dendrites (branching processes). The nerve cell receives impulses (messages) from other nerve cells at junctions called synapses. These synapses occur where the terminal boutons (small,triangular) meet the nerve cell. A close-up of a synapse is in the box at top left. The impulses are passed from the bouton (left) to the receiving cell (right) across the synapses in the form of chemical neurotransmitters (small,blue dots) | |
