AP PSYCHOLOGY

Detailed explanation-1: -Neurotransmitters that act as neuromodulators include acetylcholine, dopamine, serotonin, histamine, and cannabinoids. Some neurotransmitters, such as acetylcholine and dopamine, can create both excitatory and inhibitory effects depending upon the type of receptors that are present.

Detailed explanation-2: -Dopamine and acetylcholine are among the most important neurotransmitters in the body. They are involved in the regulation of vital functions including voluntary and involuntary movement, pain processing, pleasure, mood, smooth muscle contraction, and blood vessel dilation, among many others.

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: -Acetylcholine is the neurotransmitter at neuromuscular junctions, at synapses in the ganglia of the visceral motor system, and at a variety of sites within the central nervous system.

Detailed explanation-5: -Neurotransmitters, like dopamine, acetylcholine, glutamate and GABA are mainly involved in motor coordination and alterations in the levels of these neurotransmitters results in motor deficits.
