The site of attachment of a tendon to a movable bone is called 

Options

A. Origin of muscle
B. Aponeurosis
C. Insertion of muscle
D. Fascia

Answer

To solve the question "The site of attachment of a tendon to a movable bone is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Tendons**: Tendons are connective tissues that connect skeletal muscles to bones. They play a crucial role in facilitating movement by transmitting the force generated by muscles to the bones.

2. **Identify the Options**: The options provided are:
- Origin of muscle
- Aponeurosis
- Insertion of muscle
- Fascia

3. **Define Each Term**:
- **Origin of Muscle**: This is the fixed attachment point of a muscle, where it begins. It typically does not move when the muscle contracts.
- **Aponeurosis**: This is a type of connective tissue that connects muscles to the parts they move, but it is not specifically the site of attachment to a movable bone.
- **Insertion of Muscle**: This is the point where a tendon attaches to the movable bone. When the muscle contracts, this is the part that moves.
- **Fascia**: This is a layer of connective tissue that surrounds muscles, groups of muscles, blood vessels, and nerves, but it is not the specific site of tendon attachment.

4. **Analyze the Question**: The question specifically asks for the site of attachment of a tendon to a movable bone. Since the movable bone is where the muscle exerts its force during contraction, the correct term for this attachment is the "insertion of muscle."

5. **Select the Correct Answer**: Based on the definitions and analysis, the correct answer to the question is **insertion of muscle**.

### Final Answer:
The site of attachment of a tendon to a movable bone is called the **insertion of muscle**.
