Neurotransmitters Flashcards
Acetylcholine C7H16NO2+
Learning. Involved in thought, learning, & memory.
Activates muscle action in the body. Also
associated with attention and awakening.
Dopamine C8H11NO2
Pleasure. Feelings of pleasure, and also addiction,
movement, and motivation. People repeat
behaviours that lead to dopamine release.
Serotonin C10H12N2O
Mood. Contributes to well-being & happiness; helps
sleep cycle & digestive system regulation.
Affected by exercise & light exposure.
GABA(y-Aminobutric Acid) C4H9NO2
Calming. Calms firing nerves in CNS. High levels
improve focus; low levels cause anxiety. Also
contributes to motor control & vision.
Hormone - Norepinephrine
The primary role of norepinephrine, like adrenaline, is arousal, says Sood. “When you are stressed, you become more aware, awake, focused,” he says. “You are just generally more responsive.” It also helps to shift blood flow away from areas where it might not be so crucial, like the skin, and toward more essential areas at the time, like the muscles, so you can flee the stressful scene.
Although norepinephrine might seem redundant given adrenaline (which is also sometimes called epinephrine), Sood imagines we have both hormones as a type of backup system. “Say your adrenal glands are not working well,” he says. “I still want something to save me from acute catastrophe.”
Depending on the long-term impact of whatever’s stressing you out – and how you personally handle stress – it could take anywhere from half an hour to a couple of days to return to your normal resting state, says Sood.

Endorphins
20 Types in Human body.Released during exercise, excitement, & sex,
producing well-being & euphoria, reducing
pain. Biologically active section shown.
Glutamate C5H9N04
Memory. Most common brain neurotransmitter.
Involved in learning & memory, regulates
development & creation of nerve contacts.

development & creation of nerve contacts.
Hormone - Cortisol
A steroid hormone, commonly known as the stress hormone, produced by the adrenal glands.
What It Does: It takes a little more time – minutes, rather than seconds – for you to feel the effects of cortisol in the face of stress, says Sood, because the release of this hormone takes a multi-step process involving two additional minor hormones.
Hormone - Testosterne
Testosterone is a sex hormone primarily produced in the gonads. A small amount is also made in the adrenal glands. It is well known for its role in contributing to physical traits such as muscle strength and mass, facial and body hair, and sperm production. However, it is also involved in libido, vitality, bone density, fat distribution, and production of red blood cells to name a few of its other effects. Imbalances in this hormone can lead to decreased sexual desire, changes in sleep, reduced muscle mass and decreased self-esteem.1
