The adrenal medulla is a mass of neurons with all of the following characteristics except

Options

A. Its products are tyrosine derived
B. It releases epinephrine
C. It is responsible for the production of cortisol and aldosterone
D. It is located above the kidney

Answer

To solve the question regarding the characteristics of the adrenal medulla, we will analyze each option provided and determine which one does not accurately describe the adrenal medulla.

### Step-by-Step Solution:

1. **Understanding the Adrenal Medulla**:
- The adrenal medulla is the inner part of the adrenal glands, which are located on top of the kidneys. It primarily consists of neuroendocrine cells and is responsible for producing catecholamines (hormones).

2. **Analyzing Option A**:
- **Statement**: Its products are tyrosine derived.
- **Evaluation**: This statement is correct. The hormones produced by the adrenal medulla, such as epinephrine and norepinephrine, are indeed derived from the amino acid tyrosine.

3. **Analyzing Option B**:
- **Statement**: It releases epinephrine.
- **Evaluation**: This statement is also correct. The adrenal medulla releases epinephrine (also known as adrenaline) as one of its primary hormones.

4. **Analyzing Option C**:
- **Statement**: It is responsible for the production of cortisol and aldosterone.
- **Evaluation**: This statement is incorrect. Cortisol and aldosterone are produced by the adrenal cortex, not the adrenal medulla. Therefore, this option does not accurately describe the adrenal medulla.

5. **Analyzing Option D**:
- **Statement**: It is located above the kidney.
- **Evaluation**: This statement is correct. The adrenal medulla is located above the kidneys as part of the adrenal glands.

6. **Conclusion**:
- The only statement that does not accurately describe the adrenal medulla is Option C, which states that it is responsible for the production of cortisol and aldosterone. Therefore, the correct answer to the question is **Option C**.
