Parts of chemical synapse
WebSynapses Where two neurons meet there is a small gap called a synapse . An electrical impulse cannot directly cross the gap so a different mechanism has to be used. Web2 Feb 2024 · Connecting Parts of a Neuron: Axon Terminal and Synapse Axon terminal also called synaptic bouton or terminal button is the terminal branches of the axon located at the very end of the neuron. They are farthest from the soma and contain chemical messengers called neurotransmitters in specialized structures called synaptic vesicles.
