Question

Compare the adrenal gland of fish amphibia and mammals

Answer 1

in fish :- Secretion of adrenocortical hormones is under control of the adrenocorticotropic hormone (ACTH) of hypophysis. Chromaffin Tissue or Suprarenal Bodies or Medullary Tissue: ... Chromaffin tissue of fishes richly contain adrenaline and noradrenaline.

In amphibia :- A complex endocrine organ in proximity to the kidney. Adrenal gland tissue is present in all vertebrates from cyclostomes to placental mammals. ... In species of amphibians and fish, adrenal cells are found intermingling with kidney tissue, and the steroidogenic cells are often termed interrenal tissue.

In mammals :- In mammals, the adrenal glands (also known as the suprarenal glands) are endocrine glands that sit atop the kidneys. They are chiefly responsible for releasing three classes of hormones: Mineralocorticoids (aldosterone) Glucocorticoids (cortisol)
