The hypothalamus produces all of the following except:
Correct answer: D. ACTH
- A. CRF
- B. TRF
- C. ADH
- D. ACTH
Explanation
Option D is correct.No, the hypothalamus does not produce ACTH (adrenocorticotropic hormone). ACTH is produced by the anterior pituitary gland. The hypothalamus is a small gland that sits at the base of the brain. It is responsible for releasing hormones that control the pituitary gland. The pituitary gland is a small, pea-shaped gland that is located at the base of the brain. It is responsible for releasing hormones that control many other glands in the body, including the adrenal glands. The hypothalamus releases a hormone called corticotropin-releasing hormone (CRH) into the bloodstream. CRH travels to the pituitary gland, where it binds to receptors on the cells of the anterior pituitary gland. This binding triggers the release of ACTH from the anterior pituitary gland.ACTH then travels to the adrenal glands, where it binds to receptors on the cells of the adrenal cortex. This binding triggers the release of cortisol from the adrenal cortex. Cortisol is a steroid hormone that plays a role in the stress response, metabolism, and immune function.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
