Communication Between Neurons Anatomy and Physiology I

WebA synapse is the contact site where a neurone and another neurone or a neurone and another cell meet. The presynaptic neurone/cell is the transmitting cell; the postsynaptic neurone/cell is the receiving cell. There are two major types of synapse - electrical and chemical.
