Which joint is found between Atlas and Axis?

Options

A. Saddle joint
B. Pivot joint
C. Gliding joint
D. Hinge joint

Answer

To determine the type of joint found between the Atlas and Axis, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Anatomy**: The Atlas (C1) and Axis (C2) are the first two cervical vertebrae in the human spine. They play a crucial role in supporting the skull and allowing head movement.

2. **Identify Joint Types**: There are several types of joints in the human body, including:
- **Saddle Joint**: Allows movement in two planes but limited rotation (e.g., carpometacarpal joint of the thumb).
- **Pivot Joint**: Allows rotation around a single axis (e.g., joint between the Atlas and Axis).
- **Hinge Joint**: Allows movement in one plane (e.g., elbow and knee).
- **Ball and Socket Joint**: Allows movement in multiple axes (e.g., shoulder and hip joints).
- **Condyloid Joint**: Allows movement but not rotation (e.g., wrist joint).
- **Plane Joint**: Allows gliding movements (e.g., joints between the carpal bones).

3. **Focus on the Atlas and Axis**: The joint between the Atlas and Axis allows for significant rotational movement of the head. This is a key characteristic of a pivot joint.

4. **Conclusion**: Based on the anatomy and the type of movement allowed, the joint found between the Atlas and Axis is a **Pivot Joint**.

### Final Answer:
The joint found between the Atlas and Axis is a **Pivot Joint**.
