Neurotransmitters: The Molecules of Communication in the Nervous System - Exploring Their Role in Brain Function

Insulin is a hormone produced by the pancreas, not a neurotransmitter.

Dopamine is often referred to as the 'feel-good' neurotransmitter.

Serotonin plays a crucial role in regulating mood, sleep, and appetite.

Epinephrine, also known as adrenaline, is released in response to stress and prepares the body for action.

Glutamate is the primary excitatory neurotransmitter in the brain and plays a crucial role in memory formation.

Acetylcholine is responsible for the transmission of signals from motor neurons to muscles.

GABA is the primary inhibitory neurotransmitter in the brain and plays a role in reducing anxiety and fear.

Endorphins are natural painkillers produced by the body in response to pain and stress.

Melatonin is primarily responsible for regulating the body's circadian rhythm and sleep-wake cycles.

Retinal is a specialized neurotransmitter involved in vision, converting light into electrical signals.

Dopamine is heavily involved in reward processing, motivation, and the development of addiction.

Norepinephrine is involved in regulating various autonomic functions such as body temperature, heart rate, and blood pressure.

Acetylcholine is the primary neurotransmitter involved in muscle contraction, facilitating communication between motor neurons and muscles.
