The major target for ACTH is the:
Correct answer: D. Adrenal
- A. Pancreas
- B. Thyroid
- C. Liver
- D. Adrenal
Explanation
Adrenocorticotropic hormone (ACTH) primarily targets the adrenal cortex, adrenaline. It stimulates the adrenal glands to produce cortisol, a hormone involved in various physiological processes such as metabolism and stress response. Adrenaline, or epinephrine, is predominantly regulated by the sympathetic nervous system and released from the adrenal medulla in response to stress, playing a key role in the fight-or-flight response.

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.
