It is produced in the adrenal glands which sit atop the kidneys. Adrenalins is also referred to as epinephrine.
Adrenaline targets various organs, mainly the Heart, Blood vessels, Smooth muscles(of bronchi, uterus, gastrointestinal tract, bladder etc.), the eye (radial muscles of iris), skeletal muscles (central nervous system also, but weak effect is seen there), metabolic actions (via liver).
Adrenaline does several things for the body. It increases heart rate to help boost the supply of oxygen to muscles, begins processes to quickly break down sugar and fat, and cuts blood from the skin and stomach muscles to increase blood flow to muscles like the ones in arms and leg.
Adrenaline is a key determinant of responses to metabolic or global challenges to homeostasis, such as glucoprivation, and of manifestations of emotional distress. In contrast with the view that the sympathetic nervous and adrenomedullary hormonal systems function as a unit (the ‘sympathoadrenal system’) to maintain homeostasis in emergencies, across a variety of situations adrenaline responses are more closely linked to responses of the hypothalamic-pituitary-adrenocortical system than of the sympathetic nervous system.
Pheochromocytoma, hyperaldosteronism, virilization and Cushing's syndrome are diseases associated with hypersecretion of adrenal hormones. The adrenal gland produces hormones such as testosterone, cortisol and epinephrine. Adrenal diseases related to hyperfunction of the adrenal glands may be caused by factors that affect the glands themselves or the pituitary gland. Surgery and medications are treatment options for these diseases.
Hyper secretion or over-production of cortisol by the adrenal glands causes Cushing's Syndrome.
Hyperaldosteronism is the result of aldosterone over-production by the adrenal glands, while pheochromocytoma is associated with excessive production of catecholamines by the adrenal glands.
Virilization occurs when the adrenal glands produce high amounts of androgens such as testosterone.
