Detailed explanation-1: -Neurotransmitters are chemical messengers that your body can’t function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell. The next target cell can be another nerve cell, a muscle cell or a gland.
Detailed explanation-2: -As a result of the action potential, the chemical transmitter acetylcholine (ACh) is released into the synaptic cleft. ACh diffuses across the synaptic cleft and binds to special receptors on the postsynaptic or the postjunctional membrane.
Detailed explanation-3: -Neurotransmitter – A chemical released from a neuron following an action potential. The neurotransmitter travels across the synapse to excite or inhibit the target neuron.
