3. Postsynaptic element

9. Axon terminal branches feature varicosities (for synapses “in passing”)

11. Axosomatic: axon terminal branch synapses on a soma (cell body).

12. Axoaxonic: axon terminal branch synapses on another axon terminal branch (for presynaptic inhibition) or beside the initial segment of an axon.

14. Pre and postsynaptic plasma membranes Separated by a synaptic cleft contains glycoprotein linking material. Surrounded by glial cell processes.

15. Postsynaptic plasma membrane may appear remarkable or thickened Receptor proteins Embedded in
