Part A – Ion channels and chemical synapses Chemical synapses
transmit information from the sending (presynaptic) cell to the
receiving (postsynaptic) cell in the form of neurotransmitters. The
release of neurotransmitter into the synaptic cleft and the
resulting changes in the membrane potential of the postsynaptic
cell (postsynaptic potentials) all depend on the presence of
several different types of gated ion channels and the distribution
of these channels in the pre- and postsynaptic cells. The image
here illustrates a chemical synapse. Diagram of a chemical synapse
showing the presynaptic cell, postsynaptic cell, synaptic vesicles
containing neurotransmitters, and synaptic cleft. Letters
label parts as follows: (a) synaptic terminal, (b) presynaptic
membrane, (c) postsynaptic membrane, (d) plasma membrane of cell
body, (e) axon hillock. Drag the labels onto the table to indicate
which type(s) of gated ion channels are found in each membrane
associated with a chemical synapse. (The letters in the table refer
to the lettered structures in the image above.) Labels can be used
once, more than once, or not at all.
