Growth hormone inhibitory hormone (GHIH)

Hypothalamus

Inhibits release of growth hormone

Peptide

Anterior pituitary

Stimulates synthesis and secretion of thyroid hormones (thyroxine and triiodothyronine)

Peptide

Adrenocorticotropic hormone (ACTH)

Anterior pituitary

Stimulates synthesis and secretion of adrenocortical hormones (cortisol, androgens, and aldosterone)

Peptide

Prolactin

Anterior Pituitary

Promotes development of the female breasts and secretion of milk

Peptide

Follicle Stimulating Hormone (FSH)

Anterior Pituitary

Aldosterone

Adrenal cortex

Increases renal sodium reabsorption, potassium secretion, and hydrogen ion secretion

Steroid

Insulin

Pancreas

Promotes glucose entry in many cells, and in this way controls carbohydrate metabolism

Peptide

Parathyroid Hormone

Parathyroid

Controls serum calcium ion concentration by increasing calcium absorption by the gut and kidneys and releasing calcium from bones

Peptide

Testosterone

Testes

Promotes development of male reproductive system and male secondary sexual characteristics

Steroid

Oestrogen

Ovaries

Promotes growth and development of female reproductive system, female breasts, and female secondary sexual characteristics

Steroid

Progesterone

Ovaries

Stimulates secretion of "uterine milk" by the uterine endometrial glands and promotes development of secretory apparatus of breasts

Adrenaline: It is secreted by the adrenal glands. It is called the'fight or flight' hormone, and prepares the body to respond in emergency situations. Detailed explanation: It is secreted directly into the bloodstream and carried to different parts of the body. The target organs include the heart. As a result, the heart beats faster and that increases the supply of oxygen to the muscles. Blood supply to the digestive system and skin is reduced to contraction of muscles around small arteries in these organs. This diverts blood to the skeletal muscles. The breathing rate also increases due to the contraction of diaphragm and rib muscles.

Thyroxin: It is secreted by the thyroid gland located in the throat. It regulates the carbohydrate,fat and protein metabolism in the body to provide the best balance for growth. Iodine is essential for synthesis of thyroxin. Iodine deficiency causes goitre which results in swelling of neck.

Growth hormone: It is secreted by the pituitary galnd and is responsible for growth and development. Its deficiency causes dwarfism and excess secretion causes gigantism.

Oestrogen: It is secreted by the ovary in females. It is responsible for the changes associated with puberty in females.

Testoserone: It is secreted by the testis in males. It is responsible for changes associated with oubert in males.

Insulin: It is secretd by the pancreas. It regulates the blood sugar level. Insufficient secretion of insulin causes diabetes.
