1. Abortion
The expulsion or removal of an embryo or fetus from the mother prematurely; this can be done as an artificial procedure, but it often happens naturally when the mother's body expels the embryo/fetus because it has died, has genetic or developmental defects, or because of infection or illness in the mother. Natural abortions are typically called "miscarriages". Medically-induced abortions, which can be completed with surgery or with hormone drugs, are done because the embryo/fetus is unwanted, deformed, not likely to live, or endangers the mother's life or health.

2. Abscisic acid (ABA, abscisin)
A lipid hormone that inhibits cell growth in plants; it is associated with fruit drop, leaf death and seed dormancy. It is synthesized in the plastid s from carotenoid s. This hormone helps plants deal with water loss, and its effects can be reversed with gibberellin s.

3. Abscisic acid
A plant hormone that promotes dormancy in perennial plants and causes rapid closure of leaf stomata when a leaf begins to wilt.

4. Acetylserotonin
An acetylated (has a CH3CO- group attached) form of the hormone serotonin . Along with serotonin and the hormone melatonin , it is produced in the pineal gland in the brain .

5. Acromegaly
Acromegaly is a hormonal disorder in which there is excessive secretion of the growth hormone resulting in enlargement of hands, feet, face, tongue, jaws and internal organs. The cause is usually a benign pituitary adenoma .

6. Adrenal cortex
This is the outer portion of the adrenal gland ; it secretes hormone s such as hydrocortisone (a glucocortoid) and aldosterone (a mineralocorticoid). Glucocortoids help cells synthesize glucose , catabolize protein s, mobilize free fatty acid s, and inhibit inflammation in allergic responses. Mineralocortoids regulate the levels of minerals such as sodium and potassium in the blood.

7. Adrenal gland
This gland is found above each kidney, and it made up of an outer wall ( cortex ) that secretes important steroid hormones and an inner portion (medulla) that produces adrenaline (epinephrine) and noradrenaline (norepinephrine) .

8. Adrenocorticotrophic hormone (ACTH)
A peptide hormone produced by the anterior pituitary gland . It stimulates the adrenal cortex to secrete glucocorticoid hormones, which help cells synthesize glucose , catabolize proteins , mobilize free fatty acid s, and inhibit inflammation in allergic responses.

9. Adrenocorticotropic hormone (ACTH)
A hormone produced by the anterior pituitary that stimulates the adrenal cortex to release several hormones including cortisol.

10. Agonist
Any molecule that improves the activity of a different molecule; e.g., a hormone , which acts as an agonist when it binds to its receptor , thus triggering a biochemical response.
