Question

Cortisol is secreted from
A. Pancreas
B. Thyroid
C. Adrenal
D. Thymus

Answer 1

Hint: Cortisol is a glucocorticoid hormone, which means it's a steroid hormone. When used as a pharmaceutical, it is known as hydrocortisone. It has a diurnal cycle and responds to stress and low blood glucose levels by increasing its release.
The principal stress hormone, cortisol, boosts blood sugar (glucose), enhances glucose utilisation in the brain, and increases the availability of chemicals that repair cells. In a fight-or-flight situation, cortisol also suppresses functions that are superfluous or detrimental.

Complete answer:
Option A:Insulin and glucagon, which regulate blood glucose levels, and somatostatin, which blocks insulin and glucagon release, are the major hormones secreted by the pancreas' endocrine gland.
So option A is not correct.
Option B:Iodine from meals is used by the thyroid gland to produce two thyroid hormones: triiodothyronine (\[T3\]) and thyroxine (\[T4\]). Thyroid hormones are also stored in the body and released as needed.
So option B is not correct.
Option C: The suprarenal glands, sometimes known as the adrenal glands, are a pair of structures positioned on the top of the kidneys. Glucocorticoids are secreted mostly by the cells of the zona fasciculata of the adrenal cortex. Cortisol, corticosterone, and cortisone are the three primary hormones found in glucocorticoids. They have an impact on carbohydrate metabolism, but they also have an impact on protein and fat metabolism.
So option C is correct.
Option D: Thymosin, a hormone required for T cell growth and production, is produced and secreted by the thymus.
So option D is not correct.

So option C is the correct answer.

Note:
The examination also examines your pituitary and adrenal glands for disorders. It does so by monitoring the stress hormone cortisol in your blood. Cortisol is a steroid hormone produced by your adrenal glands. It aids your body's stress response, blood sugar regulation, and infection defence.
