The nursing student is assigned to care for an adolescent female client in the health care clinic, and the instructor reviews the menstrual cycle with the student. The instructor determines that the student understands the process of the secretion of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) if the student makes which statement? (A) "FSH and LH are secreted by the adrenal gland" (B) "FSH and LH are released from the anterior pituitary gland"(C) "FSH and LH are secreted by the corpus lutheum of the ovary"(D) "FSH and LH stimulate the formation of milk during pregnancy"

The anterior pituitary secretes the trophic hormones. Two of them are the gonadotrophic hormones, that affect the gonads (testes and ovaries). These hormones are the follicle-stimulating hormone (FSH) and the luteinizing hormone (LH). In females, these hormones help the ovocytes and the follicles to maturate. At the beginning of the female cycle, high concentrations of these hormones stimulate the ovary follicle, which grows and secretes estrogens. Under the influence of these last ones, the endometrium gets regenerated. When concentrations of estrogens get high (before the middle of the cycle), it occurs a pic in LH secretions from the hypophysis (pituitary gland), which produce the ovocyte expulsion: ovulation. After that, LH and FSH concentrations fall.
