Regulation of secretion of hormones of adrenal glands
Corticotropin-releasing factor
Corticotropin Nerve impulse
Secretion of glucocorticoids
Secretion of catecholamines
Decrease of sodium in blood plasma (increase of pottassium) Decrease of BP
Secretion of aldosterone Renin
Angiotensin II
Sexual hormonesare formed in gonads.
The specific action of sexual hormones:
1) they determine sexual differentiation of embryo
2) they promote secondary sexual features
3) they stimulate growth and development of sexual organs
4) they determine the character of fat deposition
5) they promote specific sexual behavior and functional activity of reproductive system
The total physiologic action:
They act on 2-nd mechanism and promote synthesis of adenylylcyclase. Hence, synthesis of proteins, glycogenogenolysis and lipolysis are increased. Increased synthesis of proteins leads to increase of muscular tissue and body weight. Therefore these hormones are used as anabolic medicines. Sexual hormones regulate proportional development of skeleton, inhibiting thymus (thymus increases bones in length).
Acceleration is phenomenon of a lack of sexual hormones.
