synaptic vesicles are smaller and contain amino acids and amines and synaptic granules are bigger and contain peptides

postsynaptic density

gray's type I synapses are synapses in which the postsynaptic side is thicer than that on the presynaptic side. gray's type II synapses are synapses in which the membrane differentiations are of similar thickness. gray's type I are usually excitatory while Gray's type II synapses are usually inhibitory

if the postsynaptic membrane is on a dendrite, the synapse is said to be axodendritic. If the postsynaptic membrane is on the cell body, the synapse is said to be axosomatic. Sometimes, two axons can synapse with one another, which is called axoaxonic. Two dendrites synapsing is dendrodendritic

one factor is the side of the synapse-- very large. the presynaptic terminal also contains a large number of active zones. In addition, the post-synaptic membrane, also called the motor end-plate, contains a series of shallow folds. the presynatpic active zones are precisely aligned with tese folds and the postsynaptic membrane of these folds is packed with nt receptors

amino acids, amines an peptides
