Hey guys, I need to clarify some doubts I have... Is the synaspe same as cleft? Both are known as the gap between the axon terminal and dendrites right?

"Between the pre- and postsynaptic cells is a gap about 20 nm wide called the synaptic cleft. The small volume of the cleft allows neurotransmitter concentration to be raised and lowered rapidly. The membranes of the two adjacent cells are held together by cell adhesion proteins."

This is quoted from Wikipedia. There is more there about the dendrites and axon terminal.

Chemical synapse - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Chemical_synapse#Structure)

I think the synapse refers to the entire structure, while the cleft is only the gap.

Oh.. Yeah. Because I did my research and there was this diagram showing that the synapse was from the axon terminal which is the tip of 1 neurone to the dendrite. Haha. Thanks a lot. I had clarify my doubt. Now I know what I should write for my essay.
