Adrenal Medulla
The pineal gland releases melatonin, which regulates sleep/wake cycles. The adrenal glands release epinephrine, which is the fight or flight hormone.
The adrenal glands release adrenaline, the hormone most often associated with the fight or flight response and danger.
The adrenal gland is divided into an inner adrenal medulla and an outer adrenal cortex. As the name 'adrenal' suggests, the adrenal glands secrete the peptide hormone adrenaline (epinephrine) which is involved in the fight-or-flight response. This is secreted by the adrenal medulla. The adrenal 'cortex' is involved in secreting corticosteroids, important fat-soluble hormones in the body. Since it is a gland that secretes hormones, it is known as an endocrine gland, part of the endocrine system.
epinephrine which comes from the sympathetic response (flight or fight)Adrenaline, also known as epinephrine.
The adrenal gland excretes adrenalin (epinephrin) which is a hormone that gives sudden bursts of energy to muscles. Used a response to stress. Part of the fight or flight mechanism.
That is the Adrenal gland. Another name for this is the Suprarenal gland.
it is called an emergency hormone because during emergencies and when a person feels excited. It is secreted and therefore adrenaline rush happens, which refers to an activity of the adrenal gland in a fight-or-flight response, when it is releasing adrenaline (epinephrine).
Adrenomegaly
depends on what you mean if your talking about "fight or flight" it is the adrenal gland which secretes epinephrine(adrenaline) which will speed up your heart rate but that doesn't last that long
The adrenal glands actually secrete corticosteroids. But the pituitary gland secretes a hormone that stimulates the adrenal glands to secrete the corticosteroids.
The fight or flight response happens when large amounts of adrenaline and other stress hormones surges through your body causing you to decide whether to fight (defend) or take flight (run).
