Asked in Premeth Test 20 — Coordination (Chemical and Nervous) and Respiration (22 March 2022) 2022Moderate

MSH is secreted by the

Correct answer: B. Middle lobe of pituitary

  • A. Anterior lobe of the pituitary
  • B. Middle lobe of pituitary
  • C. Posterior lobe of the pituitary
  • D. Endostyle

Explanation

Option B is correct.The middle lobe of the pituitary secretes a hormone named melanocyte-stimulating hormone. It stimulates the synthesis of the black pigment melanin in the skin, and also causes dispersal of melanin granules in the pigment cells, thereby darkening the colour in certain animals (fish, amphibians). In man, it has no such role. The anterior lobe of the pituitary secretes FSH, LH, TSH, ACTH, and STH. The posterior lobe of the pituitary secretes oxytocin and vasopressin.

About Chemical Coordination and Hormones

Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
