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 will analyze the hormones mentioned and their respective sites of production.

### Step-by-Step Solution:

1. **Identify the Hormones**:
- The hormones mentioned are:
- Epinephrine (Adrenaline)
- Norepinephrine (Noreadrenaline)
- Thyroxine
- FSH (Follicle Stimulating Hormone)
- HTH (Somatotropic Hormone)
- TSH (Thyroid Stimulating Hormone)
- Progesterone
- Testosterone
- Aldosterone (Mineralocorticoid)

2. **Determine the Sites of Production**:
- **Epinephrine and Norepinephrine**: Produced in the adrenal medulla.
- **Thyroxine**: Produced in the thyroid gland.
- **FSH, HTH, TSH**: Produced in the anterior pituitary gland.
- **Progesterone**: Produced in the ovaries (in females).
- **Testosterone**: Produced in the testes (in males).
- **Aldosterone (Mineralocorticoid)**: Produced in the adrenal cortex.

3. **Group the Hormones by Their Glands**:
- **Adrenal Gland**: Epinephrine, Norepinephrine (medulla) and Aldosterone (cortex).
- **Thyroid Gland**: Thyroxine.
- **Pituitary Gland**: FSH, HTH, TSH.
- **Ovaries**: Progesterone.
- **Testes**: Testosterone.

4. **Identify the Odd One Out**:
- Epinephrine and Norepinephrine are both produced in the adrenal medulla.
- Aldosterone is produced in the adrenal cortex.
- Thyroxine is produced in the thyroid gland.
- FSH, HTH, and TSH are produced in the anterior pituitary.
- Progesterone is produced in the ovaries.
- Testosterone is produced in the testes.

5. **Conclusion**:
- The odd one out is **Thyroxine**, as it is produced in the thyroid gland, while the others (Epinephrine, Norepinephrine, Aldosterone, FSH, HTH, TSH, Progesterone, and Testosterone) are produced in either the adrenal glands, pituitary gland, ovaries, or testes.

### Final Answer:
**Thyroxine** is the odd one out with respect to the site of hormone production.
