The Functions of the Median Lobe of the Pituitary Gland Quiz

Functions and Regulation of Melanocyte Stimulating Hormone (MSH)

• The median lobe of the pituitary gland in humans is not very prominent and is a thin layer of cells located between the anterior and posterior pituitary.
• The median lobe of the pituitary gland produces the hormone called melanocyte stimulating hormone (MSH).
• The secretion of MSH is regulated by the hypothalamic MSH inhibitory hormone.
• Melanocyte stimulating hormone (MSH) levels increase during pregnancy in humans.
• MSH stimulates the production and release of melanin by melanocytes, which are responsible for the coloration of the skin and hair.
• MSH is involved in the regulation of pigmentation in humans.
• The production and release of melanin by melanocytes is influenced by MSH.
• MSH acts as a stimulant for the production of melanin in the skin and hair.
• MSH is produced by the median lobe of the pituitary gland and acts as a hormone in the body.
• The secretion of MSH is regulated by the hypothalamus, specifically the MSH inhibitory hormone.
• MSH inhibitory hormone controls the release of MSH from the median lobe of the pituitary gland.
• MSH plays a role in the physiological changes that occur during pregnancy, such as changes in skin pigmentation.

Test your knowledge on the functions of the median lobe of the pituitary gland in humans, including its role in producing melanocyte stimulating hormone (MSH) and its regulation by hypothalamic MSH inhibitory hormone. Learn about the effects of MSH on melanin production and its changes during pregnancy.
