Question

What controls the release of hormones?
(a)Adrenal
(b)Pancreas
(c)Pituitary
(d)Thyroid

Answer 1

Hint: This is a small gland that lies under the brain and behind the bridge of the nose in the sella turcica, a bony hollow at the base of the skull. A portion of the brain (the hypothalamus) that regulates its function is connected to the gland. This gland is also known as the ‘master gland’.

Complete answer:
-There are two primary parts of the pituitary gland, the anterior pituitary gland, and the posterior pituitary gland. The posterior part produces hormones.
-The hypothalamus is a component of the brain that plays a crucial role in regulating many functions of the body, including the release of pituitary gland hormones.
-Hormones that activate the anterior portion of the pituitary gland are released by the hypothalamus. In turn, the anterior pituitary releases hormones that control the production of hormones by other endocrine glands.

Additional Information: The major hormone-releasing agents are as follows:
-The thyrotropin-releasing hormone (TRH or thyroliberin) is used by the hypothalamus to instruct the pituitary to release thyrotropin.
-Corticotropin-releasing hormones (CRH or corticoliberin) are used by the hypothalamus to tell the pituitary to release corticotropin.
-To tell the pituitary to release gonadotropin, the hypothalamus uses gonadotropin-releasing hormones (GnRH or gonadoliberin).
-To tell the pituitary to release somatotropin, the hypothalamus uses growth hormone-releasing hormone (GHRH or somatoliberin).
So, the correct answer is ‘Pituitary’

Note: -In response to changes in extracellular fluids, such as ion concentration in the blood, a humoral stimulus refers to the regulation of hormone release.
-An increase in blood glucose levels, for instance, induces the pancreatic release of insulin. Insulin allows the levels of blood glucose to fall, signaling the pancreas to stop processing insulin. This is an example of a loop of negative feedback.
