Name the muscles which are closely related with the locomotory actions and changes in body posture.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the muscles that are involved in locomotion (movement) and changes in body posture.

2. **Identifying Types of Muscles**: There are three main types of muscles in the human body: skeletal, smooth, and cardiac muscles. However, only one type is primarily responsible for locomotion and posture.

3. **Focusing on Skeletal Muscles**: Skeletal muscles are the muscles that are attached to bones and are responsible for voluntary movements. They are also known as striated muscles due to their appearance under a microscope.

4. **Role of Skeletal Muscles**: These muscles facilitate locomotion by contracting and relaxing, allowing for movement of the body. They also play a crucial role in maintaining body posture by stabilizing the skeleton.

5. **Conclusion**: The muscles closely related to locomotory actions and changes in body posture are the **skeletal muscles**.
