What is full form of FSH.
Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body.
It causes glycogenesis?
Insulin is the hormone that promotes glycogenesis, the process of converting glucose to glycogen for storage in the liver. Insulin helps lower blood glucose levels by facilitating the uptake of glucose into cells and stimulating glycogenesis. Therefore, the correct option is o2.
Which option shows correct path of Libido expression?
The correct path of Libido expression is: Leydig’s cell -----> Androgen -----> CNS -----> Libido. Leydig cells in the testes produce androgens (mainly testosterone), which then act on the central nervous system (CNS) to influence sexual drive or libido.
Which of the following is not primary endocrine gland?
The corpus luteum is not considered a primary endocrine gland.
