Read the following statements (A - D) :
1. Catecholamines secreted from adrenal medulla stimulate breakdown of glycogen resulting in an increased concentration of glucose in blood.
2. Cortisol is also involved in maintaining the cardio -vascular syem as well as kidney functions.
3. Hormone released from zona fasciculate produce anti-inflammatroy reactions and suppresses the immune response.
4. Androgenic steroids secreted by adrenal cortex play a role in growth of axial hair, pubic hair and facial hair during puberty.
How many of the above statements are ture?

Options

A. 3
B. 4
C. 2
D. 1

Answer

To determine how many of the statements (A - D) are true, we will analyze each statement one by one.

### Step 1: Analyze Statement A
**Statement A:** "Catecholamines secreted from adrenal medulla stimulate breakdown of glycogen resulting in an increased concentration of glucose in blood."

**Analysis:**
- Catecholamines, which include epinephrine (adrenaline) and norepinephrine (noradrenaline), are indeed secreted by the adrenal medulla.
- These hormones stimulate glycogenolysis, the breakdown of glycogen into glucose, which increases the concentration of glucose in the blood.

**Conclusion:** Statement A is true.

### Step 2: Analyze Statement B
**Statement B:** "Cortisol is also involved in maintaining the cardiovascular system as well as kidney functions."

**Analysis:**
- Cortisol, a glucocorticoid hormone produced by the adrenal cortex, plays a role in various bodily functions, including the regulation of metabolism and the cardiovascular system.
- It helps in maintaining blood pressure and has effects on kidney function.

**Conclusion:** Statement B is true.

### Step 3: Analyze Statement C
**Statement C:** "Hormone released from zona fasciculata produce anti-inflammatory reactions and suppresses the immune response."

**Analysis:**
- The zona fasciculata of the adrenal cortex secretes cortisol, which is known for its anti-inflammatory properties and its ability to suppress the immune response.

**Conclusion:** Statement C is true.

### Step 4: Analyze Statement D
**Statement D:** "Androgenic steroids secreted by adrenal cortex play a role in growth of axial hair, pubic hair and facial hair during puberty."

**Analysis:**
- Androgenic steroids, such as dehydroepiandrosterone (DHEA), are secreted by the adrenal cortex and contribute to the development of secondary sexual characteristics, including the growth of axial hair, pubic hair, and facial hair during puberty.

**Conclusion:** Statement D is true.

### Final Conclusion
All four statements (A, B, C, and D) are true.

**Total True Statements:** 4
