The correct Answer is:
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**. ---
