Which hormone is released by the anterior pituitary in response to corticotropin-releasing hormone (CRH) from the hypothalamus?

A. The endocrine system is responsible for voluntary actions:Voluntary actions, such as skeletal muscle movement, are controlled by the somatic nervous system, not the endocrine system.
B. Both systems use the same chemical messengers:The nervous and endocrine systems use different primary messengers—neurotransmitters for neurons and hormones for endocrine glands—although some overlap exists (e.g., norepinephrine).
C. The endocrine system is faster than the nervous system:The endocrine system typically acts more slowly because hormones travel through the bloodstream, while the nervous system acts rapidly via electrical impulses.
D. The endocrine system uses hormones, while the nervous system uses electrical impulses:The endocrine system relies on hormones carried by the blood for communication, whereas the nervous system transmits information via electrical impulses along neurons for immediate responses.

A. It directly releases cortisol into the bloodstream.:The hypothalamus does not release cortisol; cortisol is secreted by the adrenal cortex under pituitary control.
B. It secretes antidiuretic hormone (ADH) to control fluid balance.:ADH is synthesized in the hypothalamus but is stored and released from the posterior pituitary; secretion of ADH is one hypothalamic function but not the primary role in the HPA axis.
C. It inhibits the release of aldosterone from the adrenal cortex.:Aldosterone regulation is mainly via the renin–angiotensin system and potassium levels; the hypothalamus does not primarily inhibit aldosterone.
D. It secretes corticotropin-releasing hormone (CRH) to stimulate ACTH release.:The hypothalamus releases CRH, which stimulates the anterior pituitary to secrete ACTH, initiating the HPA axis cascade that leads to cortisol production.
