GENERAL HISTOLOGY

Detailed explanation-1: -Excitatory neurotransmitters “excite” the neuron and cause it to “fire off the message, ” meaning, the message continues to be passed along to the next cell. Examples of excitatory neurotransmitters include glutamate, epinephrine and norepinephrine.

Detailed explanation-2: -The postganglionic effects of autonomic ganglion cells on their smooth muscle, cardiac muscle, or glandular targets are mediated by two primary neurotransmitters: norepinephrine (NE) and acetylcholine (ACh).

Detailed explanation-3: -Neurotransmitters all serve a different purpose in the brain and body. Although there are several different minor and major neurotransmitters, we will focus on these major six: acetylcholine, dopamine, norepinephrine, serotonin, GABA, and glutamate.

Detailed explanation-4: -Four neurotransmitters come under the chemical classification of biogenic amines. These are epinephrine, norepinephrine, dopamine, and serotonin.

Detailed explanation-5: -Neurotransmitters relay their messages by traveling between cells and attaching to specific receptors on target cells. Each neurotransmitter attaches to a different receptor. For example, dopamine molecules attach to dopamine receptors. When they attach, it triggers an action in the target cells.
