The secretion of which of the following is not under the control of pituitary?

The correct answer is Adrenal medulla

Explanation:

• The pituitary gland is often referred to as the "master gland" because it controls the secretion of hormones from many other endocrine glands in the body.
• It secretes hormones like ACTH (Adrenocorticotropic hormone), TSH (Thyroid-stimulating hormone), LH (Luteinizing hormone), FSH (Follicle-stimulating hormone), and others, which regulate various glands and organs. However, not all endocrine glands are under the direct control of the pituitary gland.
  • Adrenal medulla: The secretion of hormones from the adrenal medulla is not controlled by the pituitary gland. Instead, it is regulated directly by the autonomic nervous system. The adrenal medulla secretes adrenaline (epinephrine) and noradrenaline (norepinephrine), which are involved in the "fight or flight" response. These hormones are released in response to stress and are controlled by neural signals rather than hormonal signals from the pituitary.
  • Adrenal cortex: The adrenal cortex is under the control of the pituitary gland via ACTH (Adrenocorticotropic hormone). ACTH stimulates the adrenal cortex to produce corticosteroids, such as cortisol, which play a role in stress response, metabolism, and immune regulation.
  • Thyroid: The thyroid gland is regulated by the pituitary gland through TSH (Thyroid-stimulating hormone). TSH signals the thyroid to produce and release thyroid hormones (T3 and T4), which are critical for regulating metabolism and energy balance.
  • Testis: The secretion of hormones from the testes, such as testosterone, is controlled by the pituitary gland via LH (Luteinizing hormone) and FSH (Follicle-stimulating hormone). These hormones regulate spermatogenesis and the production of androgens.
