Chemical used by neurons to send signals to each other.
What is a vesicle?
A chamber in a neuron, which stores neurotransmitter molecules. Some neurotransmitters are synthesized inside vesicles, while others are synthesized elsewhere in the neuron, and piped into vesicles for storage.
What is a synapse?
The gap between the signal-transmitting region (an axon terminal) of one neuron, and the signal-receiving portion (receptors) of an adjacent neuron.
What is monoamine oxidase?
A family of enzymes (chemicals that break down other chemicals) that metabolize (destroy) neurotransmitters.
What is dopamine?
Dopamine is typically identified as the neurotransmitter most directly associated with pleasure. "Pleasure" includes emotions such as joy, and more physically-oriented sensations such as sensuality, libido, and sexual pleasure.

What is Gamma-Aminobutyric Acid (GABA)?

What is the most common neurotransmitter?
What is Norepinephrine?
A neurotransmitter most directly associated with energy, meaning the feeling of vigor, and capacity for physical labor. It is also associated with the ability to concentrate.

The neurotransmitter most directly associated with calmness and general feelings of well-being.
Problems involving this neurotransmitter may cause severe emotional disturbance, such as dramatic over-sensitivity to disappointment, extreme melancholia, and feelings of worthlessness.

This is associated with outgoing, pleasure seeking behavior.
Opposite of GABA
GABA stands for
Gamma Aminobutyric Acid
This inhibits a variety of behaviors and emotions, reduces anxiety
_____ is abbreviated NE
This neurotransmitter is a part of the endocrine system
Beta blocker drugs block one type of _____ receptor sites
This neurotransmitter influences emergency response
Most antidepressant meds target this neurotransmitter
Low levels of this neurotransmitter are associated with impulsivity and tendency to overreact
