A synapse
a nerve tends to refer to a group of nerve cells.
Nerve messages pass from the axon of one nerve into the dendrite of another through a space separating them called the synaptic cleft.
Communication between cells.
I wouldn't use the word "occur" since a synapse is a structure, not an event, but yes, it is located between nerve cells, or more specifically, it is where the dendrites of two nerve cells meet.
The slowest dividing cells in the human body are the nerve cells. Nerve cells generate and conduct electrical impulses, allowing communication between the central nervous system and the rest of the body.
Human cells also include human nerve cell. The connections are from the nerve cell to the other cells by way of extensions called dendrites.
Are you meaning between the buttons of the first nerve cell and the dendrites of the second one? If so, then it is called the synapse or synaptic cleft!

the shape and that nerve cells have nucleus
a neurotransmitter called acetylcholine (ACh) is produced between nerve cells. This neurotransmitter carries the signal (in chemical form) at the synaptic junction.
