Question

Pituitary gland secretes which hormone from ovaries in girls?

• A. Testosterone
• B. Estrogen
• C. Insulin
• D. Thyroxine

Answer 1

The correct option is B Estrogen

The endocrine cells present in the space between seminiferous tubules are termed as interstitial cells or interstitial cells of Leydig. They serve to secrete testosterone which is responsible for the development of male secondary sexual characters.

Follicle stimulating hormone (FSH) is one of the gonadotropins secreted by anterior pituitary gland. It stimulates growth, development and hormonal secretion of Graafian follicle and ovum maturation. Developing follicles secrete estrogen which in turn stimulates the growth of the uterus and the vagina, egg maturation and development of the secondary sex characteristics in females.

Insulin is secreted by islets of Langerhans of the pancreas and serves to lower the blood glucose level by stimulating the uptake of glucose by cells, specifically muscle cells, liver cells and adipose tissues cells.

Thyroxine is a thyroid hormone which targets all tissues and stimulates metabolic rate, growth and development.

Therefore, the correct answer is option B.
