Anatomical unit of the skeletal muscle is

Options

A. Muscle fibre
B. Sarcomere
C. Muscle bundle
D. Sarcolemma

Explanation

To answer the question "What is the anatomical unit of the skeletal muscle?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the anatomical unit of the skeletal muscle. This means we need to identify the smallest structural component that makes up skeletal muscle.

2. **Identify the Options**: The options provided are:
- A) Muscle fiber
- B) Sarcomere
- C) Muscle bundle
- D) Sarcolemma

3. **Evaluate Each Option**:
- **Option A: Muscle fiber** - Muscle fibers are indeed the basic structural units of skeletal muscle. They are long, cylindrical cells that can contract and are often referred to as myofibrils. Therefore, this option is a strong candidate for the correct answer.

- **Option B: Sarcomere** - The sarcomere is the functional unit of muscle contraction, not the anatomical unit. It is the segment of a myofibril between two Z lines and is responsible for the contraction process. Thus, this option is incorrect.

- **Option C: Muscle bundle** - Muscle bundles, also known as fasciculi, are groups of muscle fibers. They are larger structures and not the smallest unit, making this option incorrect.

- **Option D: Sarcolemma** - The sarcolemma is the cell membrane surrounding a muscle fiber. While it is important for muscle function, it is not the anatomical unit of the muscle itself. Therefore, this option is also incorrect.

4. **Conclusion**: After evaluating all the options, the correct answer is **Option A: Muscle fiber**, as it is the anatomical unit of skeletal muscle.

### Final Answer:
The anatomical unit of the skeletal muscle is **Muscle fiber**.
