Question

Name two hormones secreted by the anterior lobe of pituitary gland.

Answer 1

Hint: Pituitary gland is a small pea sized gland. It plays a major role in maintaining the body functions well. It is also known as the master gland as it controls the secretion of other hormones.

Complete answer:
There are many hormones secreted by the pituitary gland. The two hormones secreted by the anterior lobe are thyroid stimulating hormone (TSH) and follicle stimulating hormone (FSH).

Additional Information: -Thyroid stimulating hormone stimulates the synthesis of the thyroid hormone from the anterior pituitary. It is also known as thyrotropin. TSH is a glycoprotein hormone. It has two subunits which are covalently bound to each other. Synthesis of thyroid hormone is essential as it controls the iodide transportation, and synthesis the thyroid peroxidase and thyroglobulin. High levels of TSH can cause endocytosis enhancement. When TSH is present at low level then the level of thyroid hormone decreases or may even get finished. TSH is inhibited by the high blood levels of thyroid hormone. This is known as the negative feedback of the hormone.
-Follicle stimulating hormone or FSH is also known as gonadotropins. It is named so as it is stimulated from the female reproductive organ which is ovaries. It is essential for the reproductive process. FSH is composed of two subunits namely, alpha and beta subunits. The gonadotroph is responsible for release of FSH in some cases it may release both LH and FSH. FSH helps in the maturation of the mammalian ovaries. For superovulation FSH are induced in humans and also in animals. FSH also helps in the maturation of the sperm cell.

Note: Luteinizing hormone or LH is also released by the pituitary gland. It is helpful in the secretion f the sex steroids. In males it stimulates the release of the testosterone. In females it causes pre ovulatory LH surge. It also helps in the release of the steroid hormone progesterone which is essential in maintaining pregnancy.
