Correct option is D
The correct answer is C and E only.
1. The posterior pituitary gland releases two major hormones: oxytocin (Option C) and vasopressin (Option E).
2. Oxytocin is involved in childbirth and lactation, stimulating uterine contractions and milk release.
3. Vasopressin, also known as antidiuretic hormone (ADH), plays a role in regulating water balance in the body by affecting kidney function.
4. Thyrotropin (Option A), follicle-stimulating hormone (Option B), and luteinizing hormone (Option D) are secreted by the anterior pituitary, not the posterior pituitary.
Information Booster
1. Posterior Pituitary Hormones:
1.1. The posterior pituitary stores and releases hormones produced by the hypothalamus, including oxytocin and vasopressin.
1.2. These hormones are produced in the hypothalamus but stored in the posterior pituitary gland before being released into the bloodstream.
1.3. Oxytocin plays a crucial role in social bonding, childbirth, and lactation.
1.4. Vasopressin regulates the kidneys' reabsorption of water and maintains blood pressure by constricting blood vessels.
1.5. Oxytocin is sometimes referred to as the "love hormone" due to its role in bonding and emotional connections.
1.6. Vasopressin’s effects on water retention and blood pressure make it essential for maintaining homeostasis in the body.
2. Anterior Pituitary Hormones:
2.1. Thyrotropin (also known as thyroid-stimulating hormone or TSH) stimulates the thyroid gland to release thyroid hormones.
2.2. Follicle-stimulating hormone (FSH) regulates the reproductive processes by stimulating the growth of ovarian follicles in females and sperm production in males.
2.3. Luteinizing hormone (LH) triggers ovulation in females and the production of testosterone in males.
2.4. These anterior pituitary hormones are essential for regulating metabolic functions, reproductive processes, and growth.
