Answer:
Explanation:
In the nervous system, a synapse is a structure that permits a
neuron (or nerve cell) to pass an electrical or chemical signal to
another neuron or to the target effector cell.
Neurotransmitter, also called chemical
transmitter or chemical messenger, any of a
group of chemical agents released by neurons
(nerve cells) to stimulate neighbouring neurons
or muscle or gland cells, thus allowing impulses
to be passed from one cell to the next throughout the nervous
system.
the synaptic cleft is the physical space between these two
neurons. the space that separates a neuron and its target cell at a
chemical synapse.
There are steps involved in synaptic transmission, which usually takes place at the neuromuscular junction.
Synapses may be chemical or electrical. In this case, it is a chemical synapse because it involves the transmission of information via chemical mediators.
The release of neurotransmitter molecules into the synaptic cleft is triggered by the influx of calcium ions via voltage-gated ion channels.
