Find the odd one out with respect to the site of hormone production

Options

A. Epinephrine, nor -epinephrine, thyroxine
B. FSH, STH, TSH
C. Progesterone, testosterone, mineralocorticoid
D. Insulin, glucagon, oxytocin

Answer

To solve the question of finding the odd one out with respect to the site of hormone production, we need to analyze each option based on the glands that produce the hormones mentioned.

### Step-by-Step Solution:

1. **Identify the hormones and their respective glands in each option:**
- **Option 1:** Epinephrine, Norepinephrine, Thyroxine
- Epinephrine and Norepinephrine are produced by the **adrenal medulla**.
- Thyroxine is produced by the **thyroid gland**.
- **Option 2:** FSH, STH, TSH
- FSH (Follicle Stimulating Hormone), STH (Somatotropic Hormone), and TSH (Thyroid Stimulating Hormone) are all produced by the **pituitary gland**.
- **Option 3:** Progesterone, Testosterone, Mineralocorticoids
- Progesterone is produced by the **ovaries**.
- Testosterone is produced by the **testes**.
- Mineralocorticoids are produced by the **adrenal cortex**.
- **Option 4:** Insulin, Glucagon, Oxytocin
- Insulin and Glucagon are produced by the **pancreas**.
- Oxytocin is produced by the **pituitary gland**.

2. **Analyze the production sites:**
- **Option 1:** Involves two different glands (adrenal medulla and thyroid gland).
- **Option 2:** All hormones produced by the same gland (pituitary gland).
- **Option 3:** Involves three different glands (ovaries, testes, adrenal cortex).
- **Option 4:** Involves two different glands (pancreas and pituitary gland).

3. **Determine the odd one out:**
- The second option (FSH, STH, TSH) is the only option where all hormones are produced by the same gland (pituitary gland). The other options involve hormones produced by different glands.

### Conclusion:
The odd one out is **Option 2: FSH, STH, and TSH** because all three hormones are produced by the same gland (pituitary gland), while the other options consist of hormones produced by different glands.
