Problem:
Question: What is the circadian pattern of ACTH release, and what endocrine gland releases it?
- ACTH is not a hormone so it is not released from an endocrine gland
- The anterior pituitary will release more ACTH at night, and less during the day
- The hypothalamus will release less ACTH at night, and more during the day, particularly before noon.
- ACTH is not released in a circadian pattern.
Please Explain don't just write the answer.
