 Which among the following is called growth inhibiting hormone?

1

Somatostatin

Correct Answer

2

Gonadotrophin releasing hormone

3

Oxytocin

4

vasopressin

Explanation:

• The hormones produced by the hypothalamus are of two types, the releasing hormones (which stimulate secretion of pituitary hormones) and the inhibiting hormones (which inhibit secretions of pituitary hormones).

1. Releasing hormone - Gonadotrophin releasing hormone (GnRH) stimulates the pituitary synthesis and release of gonadotropins.
2. Inhibiting hormone -  Somatostatin from the hypothalamus inhibits the release of growth hormone from the pituitary.

• Thereby, Somatostatin is called the growth inhibiting hormone.

  

• Somatostatin is a hormone produced by many tissues in the body such as the hypothalamus, pancreas, etc.
• It is an inhibiting hormone that inhibits the secretion of other hormones.
• Somatostatin secreted by the delta cells of the pancreas inhibits the secretion of other pancreatic hormones like insulin and glucagon.

Additional Information

Vasopressin - 

• It is also called the Antidiuretic hormone secreted by the posterior pituitary gland.
• It mainly acts on the kidney and stimulates the reabsorption of water by the distal convoluted tubules and thereby reduces the loss of water through urine (Diuresis) so-called antidiuretic hormone.

Oxytocin -

•  It is synthesized by the hypothalamus and is transported axonally to the neurohypophysis.
• Oxytocin acts on the smooth muscles of our body and stimulates their contraction. In females, it stimulates a vigorous contraction of the uterus at the time of childbirth, and milk ejection from the mammary gland. For this reason, it is also called the birth hormone.
