Which hormones are antagonistic in nature?

Hormone pairs like growth hormone – somatostatin, calcitonin – parathormone and insulin – glucagon, are antagonistic in nature. They constantly fight against each other to maintain homeostasis within the body.

Which of the following is an example of the permissiveness of hormones?

Thyroid hormones and glucocorticoids are examples of ‘permissive’ hormones that exert profound effects on the ability of cells to respond to other hormones, such as catecholamines.

Is relaxin and inhibin antagonistic?

Explanation: Relaxin and Inhibin are not antagonistic and have different functions. Relaxin is secreted by the placenta and ovaries. Inhibin is secreted by granulosa cells of ovaries and inhibits the secretion of FSH from the anterior pituitary.

Is aldosterone and ANF antagonistic?

Atrial natriuretic factor (ANF) antagonizes vasoconstriction induced by numerous smooth muscle agonists and also lowers blood pressure in intact animals. ANF also reduces plasma aldosterone in vivo and inhibits basal and agonist-induced aldosterone release from isolated adrenal cortical cells.

Which of the following is an example of permissiveness?

Which of the following two hormones have antagonistic effect?

Glucagon and insulin are antagonistic hormones.

Which pair of hormones are antagonistic?

Antagonistic hormones are a pair of hormones that function in opposites. Glucagon and insulin are antagonistic hormones. Glucagon functions to increase blood sugar levels and insulin works to decrease the same.

Which is antagonistic to Ras?

Angiotensin II, the major effector peptide of the renin–angiotensin system (RAS), binds to two major receptors, AT1 and AT2, that generally oppose each other.

Which hormone is antagonistic to calcitonin?

Parathyroid hormone (PTH)
Parathyroid hormone (PTH) is essential for the physiologic maintenance of mineral homeostasis. PTH regulates the mineral transport in bone and kidney and through its secondary actions on mineral transport in intestine (mediated by 1.25 (OH)2D). Calcitonin, in many ways, acts as a physiologic antagonist to PTH.
