Adrenaline, also known as epinephrine, is a hormone and medication [10] [11] which is involved in regulating visceral functions (e.g., respiration). [10] [12] It appears as a white microcrystalline granule. [13] Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. [14]
Early experiments showed that adrenaline increases twitch, but not tetanic force and rate of force development in muscles. [38]One proposed explanation is Tim Noakes' "central governor" theory, which states that higher instances in the central nervous system dynamically and subconsciously control the number of active motor units in the muscle.
Epinephrine, also known as adrenaline, is a medication and hormone. [ 10 ] [ 11 ] As a medication, it is used to treat several conditions, including anaphylaxis , cardiac arrest , asthma , and superficial bleeding. [ 8 ]
The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta blockers, beta-2 (β 2) antagonists and alpha-2 (α 2) agonists, which are used to treat high ...

An adrenergic storm is a sudden and dramatic increase in serum levels of the catecholamines adrenaline and noradrenaline (also known as epinephrine and norepinephrine respectively), with a less significant increase in dopamine transmission.

Adrenaline is released by the adrenal glands to begin the response in the body. Adrenaline acts as a catalyst for the fight-or-flight response, [11] which is a response of the sympathetic nervous system to encourage the body to react to the apparent stressor. This response causes an increase in heart-rate, blood pressure, and accelerated breathing.
