Nerve ending. Coloured scanning electron micrograph (SEM) of a nerve ending (synapse) that has been broken open to reveal the synaptic vesicles (rounded) beneath the cell membrane. A synapse is the point where two nerve ending meet (or where a nerve meets another cell type). The electrical impulse moving along a nerve is transmitted across the synaptic gap by chemicals called neurotransmitters. Stored in synaptic vesicles,they are released when voltage-dependent calcium channels are triggered | |
