Hormone whose site of synthesis is different from site of release is

Options

A. Antidiuretic hormone
B. Luteinising hormone
C. Prolactin
D. Melanocyte stimulating hormone

Explanation

To answer the question "Hormone whose site of synthesis is different from the site of release is," we can follow these steps:

### Step 1: Understand the Question
The question is asking for a specific hormone that is produced (synthesized) in one location but released in another. This is a key characteristic of certain hormones in the endocrine system.

**Hint:** Look for hormones that have a distinct production site and a separate release site.

### Step 2: Identify Relevant Hormones
We need to consider various hormones and their synthesis and release sites. For instance:
- **Antidiuretic Hormone (ADH)** and **Oxytocin** are two hormones produced in the hypothalamus.
- **Luteinizing Hormone (LH)** and **Prolactin** are produced and released by the anterior pituitary.

**Hint:** Focus on hormones that are known to be produced in the hypothalamus but released from the pituitary gland.

### Step 3: Analyze the Hypothalamus-Pituitary Connection
ADH and Oxytocin are synthesized in the hypothalamus and travel down the axons to the posterior pituitary (neurohypophysis), where they are released into the bloodstream. This clearly shows that their site of synthesis (hypothalamus) is different from their site of release (posterior pituitary).

**Hint:** Consider the hypothalamus as a key player in the endocrine system and how it interacts with the pituitary gland.

### Step 4: Confirm Other Hormones
For completeness, we should confirm that other hormones like LH, Prolactin, and Melanocyte Stimulating Hormone (MSH) are synthesized and released from the same location (anterior pituitary). This confirms they do not fit the criteria of the question.

**Hint:** Compare the synthesis and release sites of other hormones to ensure they do not meet the criteria.

### Step 5: Conclusion
Based on the analysis, the hormone whose site of synthesis is different from the site of release is **Antidiuretic Hormone (ADH)**. It is synthesized in the hypothalamus and released from the posterior pituitary.

**Final Answer:** Antidiuretic Hormone (ADH)
