Signal Transmission At A Chemical Synapse — a labelled NEET Biology diagram with a definitions lexicon.
Signal Transmission at a Chemical Synapse Labelled parts: Pre-synaptic terminal, Synaptic vesicles, Neurotransmitters, Synaptic cleft, Receptors, Post-synaptic membrane, Calcium channels. A junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter. A chemical substance released at the end of a nerve fiber by the arrival of a nerve impulse. The space between the pre-synaptic and post-synaptic membranes. Small membranous sacs containing neurotransmitters within the pre-synaptic terminal.
