The sheath covering the bundle of muscle fibres is
1) Epimysium
2) Endomysium
3) Perimysium
4) Mesoderm

Options

A. Epimsium
B. Endomysium
C. Perimysium
D. Mesoderm

Answer

To solve the question regarding the sheath covering the bundle of muscle fibers, we will analyze each option step by step.

### Step 1: Understand the Options
The question provides four options:
1. Epimysium
2. Endomysium
3. Perimysium
4. Mesoderm

### Step 2: Define Each Term
- **Epimysium**: This is a connective tissue that surrounds the entire muscle.
- **Endomysium**: This is the connective tissue that wraps around each individual muscle fiber.
- **Perimysium**: This is the fibrous sheath that covers a bundle of muscle fibers, also known as a fascicle.
- **Mesoderm**: This is one of the three primary germ layers in the early embryo, not directly related to muscle fiber sheaths.

### Step 3: Identify the Correct Answer
The question specifically asks for the sheath covering a bundle of muscle fibers. The correct term for this is **Perimysium**, as it surrounds each fascicle of muscle fibers.

### Step 4: Eliminate Incorrect Options
- **Epimysium** is incorrect because it covers the entire muscle, not just the bundles.
- **Endomysium** is incorrect because it wraps individual muscle fibers, not bundles.
- **Mesoderm** is incorrect as it refers to a developmental layer, not a muscle sheath.

### Conclusion
The correct answer is **3) Perimysium**.
