Transaction of pituitary stalk leads to:



A Increase in ACTH

B Increase in prolactin

C Increase in growth hormone

D Increase in TSH

Ans. B Increase in prolactin
  1. The pituitary is under the control of the hypothalamus, which produces a number of chemical mediators.
  2. These hormones are synthesized in the hypothalamus and enter the portal vascular system, which carries them through the PITUITARY STALK to the anterior lobe Interruption of the pituitary stalk is followed by reduction in the release of Growth Hormone, luteinizing hormone, Follicle Stimulation Hormone, thyroid-stimulating hormone, and adrenocorticotropic hormone, from the anterior pituitary.
  3. In contrast the LEVEL OF PROLACTIN RISES after interruption of the stalk, implying that the normal hypothalamic influence on prolactin secretion is inhibitory Q
