Question

Vasopressin is responsible for

• A. Controlling oogenesis
• B. Regulating blood pressure and act on the nephron tubules
• C. Regulating formation of pigment
• D. Controlling spermatogenesis

Answer 1

The correct option is B Regulating blood pressure and act on the nephron tubules

Vassopressin/antidiuretic hormone (ADH) is secreted by posterior pituitary gland and targets nephron tubules to increase water reabsorption and thereby decreasing water content in urine while increasing that of blood. Increased water concentration in blood raises blood volume and blood pressure. Under conditions of lower blood pressure, vasopressin secretion is inhibited. MSH stimulates melanin production from melanocytes. Follicle stimulating hormone (FSH) regulates oogenesis and spermatogenesis. Thus, the correct answer is option B.
