ANATOMY

Detailed explanation-1: -Glutamate is the primary excitatory neurotransmitter in the brain. Exposure to stressors and the release of, or administration of, glucocorticoids activates glutamate release in the brain.

Detailed explanation-2: -Epinephrine. Epinephrine (also known as adrenaline) plays a role in the body’s “fight-or-flight” response. It is both a hormone and a neurotransmitter. When a person experiences stress or fear, their body releases epinephrine .

Detailed explanation-3: -Catecholamines include neurotransmitters such as dopamine, epinephrine (adrenaline) and norepinephrine (noradrenaline), which are released during the body’s stress response.

Detailed explanation-4: -Endorphins are created in your pituitary gland and hypothalamus, both located in the brain. Endorphins are a type of neurotransmitter, or messenger in your body. They attach to your brain’s reward centers (opioid receptors) and carry signals across your nervous system.

Detailed explanation-5: -Exercise and Stress -Endorphin is released from the pituitary into the blood during stress [33] and exercise [1]. It has been reported to mediate the euphoria experienced in pro longed exercise and to inhibit postexercise pain. Plasma -endorphin has a number of actions on the periphery during exercise.
