Question

Quizplus · Accepted Answer

The menstrual cycle is regulated by hormones from both the anterior pituitary gland and the ovary. The anterior pituitary gland secretes follicle-stimulating hormone (FSH) and luteinizing hormone (LH) which stimulate the growth and maturation of ovarian follicles. The ovary produces estrogen which thickens the uterine lining and prepares it for implantation. Progesterone, also produced by the ovary, maintains the uterine lining for implantation. Therefore, both the anterior pituitary gland and the ovary contribute to the hormonal regulation of the menstrual cycle. The posterior pituitary gland is not involved in the menstrual cycle.
