What statement describes the synapse

The synapse is a gap-shaped structure about 20 nm wide that separates neurons and is essential for neuronal function. It is located in the nervous system and allows a nerve cell to send electrical or chemical signals to another neuron.

The synapse is the means by which neurons send signals to cells.

The neuron that emits the signal (presynaptic neuron) has a plasma membrane, which enters into close apposition with the cell membrane that receives the message (postsynaptic). Between the two cells there is a large number of molecules that bind the two membranes and carry out the signaling process. There are cells that perform key functions for the realization of nerve activity and are called astrocytes, which also exchange information with synaptic neurons, and influence synaptic activity, regulating neurotransmission.

Synapses ensure their position through synaptic adhesion molecules (SAM) which join where pre and post synaptic neurons overlap and also help in the generation and functioning of synapses.
