Chemical messengers that pass the neural impulse across the synaptic cleft are called ____
A
neuroglial cells
B
dendrites
C
axon terminals
D
neurotransmitters
Explanation: 

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: -Neurotransmitters are often referred to as the body’s chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles. Communication between two neurons happens in the synaptic cleft (the small gap between the synapses of neurons).

Detailed explanation-4: -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.
