Adrenal Cortex
Probably more hormones-more than three dozens - are produced by the adrenal cortex than by any other endocrine gland of the body. A number of these hormones are essential to life. The cortex is closely related to the organs of reproduction. The secretions of the cortex stimulate the healthy growth of the brain and sex-cells, develop great mental concentration and physical endurance and generate a vigorous muscular and nervous constitution. So close are the brain and adrenal cortex related that a normal human brain never develops without a normal adrenal cortex.
Fifty steroid compounds have been isolated from the adrenal cortex to date. Functionally, the adrenal-cortical hormones can be grouped into three major classes : :
(i) Mineralocorticoids which influence primarily the electrolytes of the extra-cellular fluids, regulate the quantity of salt and water and maintain the electrolyte balance in the body.
(ii) Glucocorticoids which act primarily on the carbobydrate-, protein- and fat-metabolism and help fight stressful conditions (infection toxicosis, injury etc.) by raising the blood-glucose-level. They are secreted in response to ACTH released from the pituitary.
(iii) The sex hormones (both male and female).
Two of the most important hormones are : (a) Aldosterone, belonging to the first group, and
(b) Cortisone which is converted to hydrocortisone, from the second one. Cortisone is nowadays synthesizec and used in treatment of many different disorders mostly to suppress inflammation. Pain in muscles and joints are ofter dramatically affected and relieved by the use of this drug. Tbe Adrenal Medulla
The adrenal medulla has a loose structure; it is abou one-tenth the size of the cortex. It secretes two importan hormones :
(i) Epinephrine-also called adrenaline. (ii) Norepinephrine (noradreealine).
