Skeletal muscles have a striped appearance under the microscope and hence called____mucles.

Answer

**Step-by-Step Solution:**

1. **Understanding Skeletal Muscles**: Skeletal muscles are the muscles that are attached to the skeleton and are responsible for voluntary movements of the body. They are found in various parts of the body, including the limbs.

2. **Microscopic Appearance**: When observed under a microscope, skeletal muscles exhibit a distinctive striped or banded appearance. This characteristic is crucial for identifying these muscles.

3. **Terminology**: The striped appearance of skeletal muscles is due to the arrangement of protein filaments within the muscle fibers. These filaments are primarily actin (thin filaments) and myosin (thick filaments).

4. **Striated Muscles**: Because of their striped appearance, skeletal muscles are referred to as "striated muscles." The term "striated" comes from the Latin word "stria," meaning "stripe" or "furrow."

5. **Conclusion**: Therefore, the answer to the question is that skeletal muscles are called "striated muscles" due to their striped appearance under the microscope.

**Final Answer**: Skeletal muscles have a striped appearance under the microscope and hence called **striated muscles**.
