This hormone from the hypothalamus stimulates release of ACTH from the anterior pituitary:
Correct answer: C. CRH
- A. STHRRH
- B. TRH
- C. CRH
- D. ACTH
Explanation
Corticotropin-releasing hormone (CRH) from the hypothalamus stimulates the release of adrenocorticotropic hormone (ACTH) from the anterior pituitary. CRH binds to receptors on corticotroph cells in the anterior pituitary, triggering the synthesis and secretion of ACTH. ACTH then stimulates the adrenal glands to produce and release cortisol, initiating the body's stress response and regulating various physiological processes such as 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.
