Question

Expain the functions of hormones secretef by Pituitary gland.

Answer 1

Explanation:

Hormones secreted from the pituitary gland help to control growth, blood pressure, energy management, all functions of the sex organs, thyroid glands and metabolism as well as some aspects of pregnancy, childbirth, breastfeeding, water/salt concentration at the kidneys, temperature regulation and pain relief.

Answer 2

Answer:

Some of the hormones secreted by anterior pituitary gland are:

• Growth Hormone: Also called as the somatotropin hormone. It affects the cells that undergo growth and stimulates growth by increasing protein, fat and carbohydrate metabolism. Hyposecretion caused gigantism while hypersecretion causes dwarfism.
• Follicle Stimulating Hormone: In females, helps in the growth of ovarian follicles till ovulation and in males, helps in the growth of seminiferous tubules and in spermatogenesis.
• Luetinizing Hormone: Also called as the interstitial cell stimulating hormone. Stimulates the development of interstitial cells in male and stimulates production of oestrogen and progesterone in females.
• Prolactin: Stimulates the mammary glands for lactation. Previously called as the Luteotropic hormone.
• Adrenocorticotropic Hormone: It stimulates secretion of hormones from adrenal cortex. Increases the concentration of cholestrol and steroids.
• Thyroid Stimulating Hormone: Promotes growth and proper functioning of thyroid gland. Stmulates secretion of thyroxine.
• Lipolytic Hormone: It stimulates fatty acid liberation from adipose tissue. Hyposecretion causes obesity and hypersecretion causes emaciation.

Some hormones secreted by the posterior part of pituitary gland are :

• Oxytocin: Initiates vigorous uterine contractions in females at the time of childbirth. Stimulates adenohypophysis to secrete prolactin.
• Vasopressin: It causes contraction of blood vessels and increases the blood pressure. Helps in the reabsorptionof water from nephrons in the kidney.
