Q155 / 180 · NEET 2017 · Zoology

GnRH, a hypothalamic hormone, needed in reproduction, acts on

  • A
    Anterior pituitary gland and stimulates secretion of LH and oxytocin
  • Correct answer
    B
    Anterior pituitary gland and stimulates secretion of LH and FSH
  • C
    Posterior pituitary gland and stimulates secretion of oxytocin and FSH
  • D
    Posterior pituitary gland and stimulates secretion of LH and relaxin

Solution

Hypothalamus secretes GnRH which stimulates anterior pituitary gland for the secretion of gonadotropins (FSH and LH). GnRH is a releasing hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. GnRH is a trophic peptide hormone synthesized and released from GnRH neurons within the hypothalamus.

Hence, the correct answer is option: 'B'.
