Choose the Odd One Out Growth hormone , TSH , vasopressin , LH.

Answer

To solve the question "Choose the Odd One Out: Growth hormone, TSH, vasopressin, LH," we can follow these steps:

### Step 1: Identify the hormones listed
The hormones mentioned in the question are:
- Growth hormone (GH)
- Thyroid-stimulating hormone (TSH)
- Vasopressin (also known as ADH)
- Luteinizing hormone (LH)

### Step 2: Classify the hormones based on their origin
Next, we need to classify these hormones based on where they are produced:
- **Growth hormone (GH)**: Produced by the anterior pituitary gland.
- **Thyroid-stimulating hormone (TSH)**: Also produced by the anterior pituitary gland.
- **Luteinizing hormone (LH)**: Produced by the anterior pituitary gland.
- **Vasopressin (ADH)**: Produced by the posterior pituitary gland.

### Step 3: Determine the odd one out
Now, we can see that:
- Growth hormone, TSH, and LH are all produced by the anterior pituitary gland.
- Vasopressin is produced by the posterior pituitary gland.

### Conclusion
Since vasopressin is the only hormone that comes from the posterior pituitary, it is the odd one out.

**Final Answer**: Vasopressin
