Injury to adrenal cortex is not likely to affect secretion of

Options

A. Androstenedione and dehydroepiandrosterone
B. Adrenaline
C. Cortisol
D. Aldosterone.

Answer

To solve the question, "Injury to adrenal cortex is not likely to affect secretion of," we need to understand the structure and function of the adrenal gland, which consists of two main parts: the adrenal cortex and the adrenal medulla.

### Step-by-Step Solution:

1. **Identify the Structure of the Adrenal Gland**:
- The adrenal gland is divided into two main regions: the outer adrenal cortex and the inner adrenal medulla.

2. **Understand the Functions of Each Part**:
- The adrenal cortex is responsible for producing hormones such as cortisol, aldosterone, and androgens (like dehydroepiandrosterone).
- The adrenal medulla produces catecholamines, primarily adrenaline (epinephrine) and norepinephrine.

3. **Analyze the Effects of Injury to the Adrenal Cortex**:
- If there is an injury to the adrenal cortex, the production of hormones like cortisol, aldosterone, and androgens will be affected.
- However, the adrenal medulla functions independently of the adrenal cortex.

4. **Determine Which Hormone Secretion Will Not Be Affected**:
- Since the adrenal medulla is not impacted by an injury to the adrenal cortex, the secretion of adrenaline will remain unaffected.

5. **Conclusion**:
- Therefore, the correct answer to the question is that injury to the adrenal cortex is not likely to affect the secretion of adrenaline.

### Final Answer:
Injury to the adrenal cortex is not likely to affect the secretion of adrenaline.
