Which hormone is primarily responsible for milk ejection from the mammary gland during milking?
Correct answer: B. Oxytocin
- A. Prolactin
- B. Oxytocin
- C. Progesterone
- D. Follicle-stimulating hormone
Explanation
Oxytocin causes contraction of the myoepithelial cells surrounding the alveoli, forcing milk into the ducts. Prolactin supports milk synthesis, but it does not directly produce the milk ejection reflex.
