The hormones FSH and LH that regulate the menstrual cycle are secreted by the
- A. ovary
- B. anterior pituitary gland
- C. uterus
- D. thyroid gland
Explanation
The anterior pituitary releases both gonadotropins under direction from hypothalamic GnRH. The ovary responds to them by producing oestrogen and progesterone, so the control runs from the brain to the ovary, not the reverse.
