- Prolactin

- Oxytocin
Solution
The answer is the first one: Prolactin.
Explanation for each option:
Prolactin: This is the correct answer. Prolactin is the hormone produced by the anterior pituitary gland that stimulates the mammary glands to produce milk.
ACTH (Adrenocorticotropic Hormone): This hormone stimulates the adrenal glands to release cortisol but does not play a role in milk production.
TSH (Thyroid-Stimulating Hormone): This hormone stimulates the thyroid gland to produce thyroid hormones but is not involved in milk synthesis.
Oxytocin: Although oxytocin is involved in milk ejection (let-down reflex) during breastfeeding, it is not responsible for the synthesis of milk.
Summary:
The anterior pituitary hormone that stimulates the mammary glands to synthesize milk is Prolactin.
