Adrenaline

4 views

A substance produced by the medulla (inside) of the adrenal gland, adrenaline (the official name in the British Pharmacopoeia) is synonymous with epinephrine.

Technically speaking, adrenaline is a sympathomimetic catecholamine.

It causes quickening of the heart beat, strengthens the force of the heart's contraction, opens up the bronchioles in the lungs and has numerous other effects.

The secretion of adrenaline by the adrenal is part of the 'fight-or-flight' reaction that we have in response to being frightened.
