The Question
Which gland is responsible for the secretion of prolactin?
A Thyroid gland
B Adrenal gland
C Ovary
D Pituitary gland
Details
💡 Hint
This hormone is essential for milk production. Which gland is known for controlling many other endocrine glands and is located in the brain?
📝 Solution Steps
- Step 1: Identify the hormone in question: prolactin.
- Step 2: Recall the primary function of prolactin.
- Step 3: Associate prolactin with the gland responsible for its production.
- Step 4: Briefly review the functions of the other glands listed to confirm the correct answer.
📚 Explanation
Prolactin is a hormone primarily responsible for stimulating milk production (lactation) in mammals after childbirth. It is secreted by the anterior lobe of the pituitary gland. The pituitary gland, often called the ‘master gland,’ is located at the base of the brain and plays a crucial role in regulating many other endocrine glands and bodily functions. The thyroid gland produces thyroid hormones (metabolism), the adrenal gland produces adrenaline and corticosteroids (stress response, metabolism), and the ovary produces estrogen and progesterone (female reproductive cycle).
✅ Answer
D
⚠️ Common Mistakes
- Confusing prolactin with oxytocin (which causes milk ejection, not production) or misattributing its secretion to other glands.
