Which of the following hormone is released from hypothalamus?
The question's correct answer is likely one of these. Let's say the options were CRH, ACTH, TSH, and FSH. Then CRH would be correct because ACTH is from the pituitary, TSH and FSH are from the pituitary as well. Wait, but the user hasn't provided the actual options. Hmm. The user's example shows the question as "Which of the following hormone is released from hypothalamus?" with options A to D, but they are empty. The correct answer placeholder is also empty. Maybe the user intended to provide the actual options and answer in their own question but forgot. But since I need to generate a sample based on the structure, I should create a plausible example.
Let me create a sample question. Suppose the options are:
A. Corticotropin (ACTH)
B. Thyroid-stimulating hormone (TSH)
C. Follicle-stimulating hormone (FSH)
D. Corticotropin-releasing hormone (CRH)
Then the correct answer would be D. CRH. Now, the core concept here is that the hypothalamus releases CRH, which stimulates the anterior pituitary to release ACTH. The incorrect options (ACTH, TSH, FSH) are all pituitary hormones.
In the explanation, I need to detail why CRH is correct, mention the pathway (hypothalamic-pituitary-axis), and explain why each wrong option is wrong. Also, the clinical pearl could be a mnemonic or a key fact, like remembering that the hypothalamus releases releasing hormones, while the pituitary releases the actual hormones.
I need to make sure the explanation is concise but covers all required sections. Check the character count to stay within 2,500. Use bold for section headers and key terms. Avoid markdown headings. Let me draft that now.
**Core Concept**
The hypothalamus secretes **releasing and inhibiting hormones** that regulate pituitary gland function. Key examples include **corticotropin-releasing hormone (CRH)**, **gonadotropin-releasing hormone (GnRH)**, and **thyrotropin-releasing hormone (TRH)**. These hormones act on the anterior pituitary to modulate the release of pituitary hormones.
**Why the Correct Answer is Right**
**CRH** is synthesized in the hypothalamus and transported via the hypophyseal portal system to the anterior pituitary. It stimulates the release of **adrenocorticotropic hormone (ACTH)** from the anterior pituitary, which in turn drives cortisol production by
