Question 1 of 5
Which structure controls the hormones secreted by the pituitary gland?
Correct Answer: A
Rationale: The correct answer is the hypothalamus. The hypothalamus is a region of the brain located below the thalamus that plays a crucial role in controlling the pituitary gland. It releases hormones that either stimulate or inhibit hormone production in the pituitary gland, thus regulating various bodily functions. The adrenal gland, testes, and pancreas do not directly control the hormones secreted by the pituitary gland.

Which hormone stimulates milk production in the breasts during lactation?
Correct Answer: C
Rationale: Prolactin is the hormone responsible for stimulating milk production in the breasts during lactation.

While norepinephrine, antidiuretic hormone, and oxytocin have roles in various physiological processes, they do not directly stimulate milk production. Therefore, the correct answer is prolactin.
