What are adrenals glands?
Adrenal glands are small, triangular-shaped endocrine glands located on the top of each kidney. They are about 3 inches wide, and a half inch high.
The Adrenal Cortex
The adrenal cortex consists of three different sections. Each section produces a different type of hormones. Cortical hormones are considered steroids. The outer part of the adrenal cortex secrets Minerallocorticoids. The main mineralcorticoid is aldosterone. This job of it is to conserve sodium ions and water in your body.
The middle section of the adrenal cortex secretes glucocorticoids. The main glucocorticoid is cortisol. The duty of cortisol is to increase blood glucose levels.
The innermost region of you adrenal cortex has the duty of secreting steroids called gonadocorticoids. These are otherwise known as sex hormones. The hormones adrogens, in males, and estrogens in females are secreted in small amounts by the adrenal cortex.
The Adrenal Medulla
The adrenal medulla develops from neural tissue and secretes the two hormones called epinephrine and norepinephrine. These two hormones are secreted in response to stimulation by sympathetic nerve, particularly during stressful situations. A lack of hormones from the adrenal medulla produces no significant effects.
