All of the following are functions of adrenaline except :

Options

A. Increases blood supply in skeletal muscle
B. Hyperglycaemia
C. Uterine relaxation
D. Tachycardia

Answer

To solve the question "All of the following are functions of adrenaline except:", we will analyze each option provided to determine which one does not correspond to the functions of adrenaline.

### Step-by-Step Solution:

1. **Understand the Role of Adrenaline**:
Adrenaline, also known as epinephrine, is a hormone produced by the adrenal glands. It plays a crucial role in the body's fight-or-flight response, which prepares the body to respond to stress or danger.

2. **Evaluate Each Option**:
- **Option 1: Increases blood supply in the skeletal muscle**:
This is a function of adrenaline. During stressful situations, adrenaline increases blood flow to the muscles, enhancing physical performance.

- **Option 2: Hyperglycemia**:
Adrenaline does promote hyperglycemia by stimulating the liver to release glucose into the bloodstream. Thus, this option is also a function of adrenaline.

- **Option 3: Uterine relaxation**:
This is not a function of adrenaline. Uterine relaxation is primarily influenced by the hormone relaxin, which is secreted during pregnancy. Therefore, this option does not correspond to the functions of adrenaline.

- **Option 4: Tachycardia**:
Adrenaline increases heart rate, leading to tachycardia (rapid heartbeat). This is indeed a function of adrenaline.

3. **Identify the Correct Answer**:
Based on the evaluation, the correct answer is **Option 3: Uterine relaxation**, as this is not a function of adrenaline.

### Final Answer:
The correct answer is **Option 3: Uterine relaxation**.
