The joint of our neck which allows us to rotate our head left to right is :-

Options

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

Answer

**Step-by-Step Solution:**

1. **Identify the Type of Joint**: The question asks about the joint in our neck that allows us to rotate our head from left to right. We need to consider the types of joints that facilitate this movement.

2. **Understand Joint Types**: There are several types of joints in the human body:
- **Pivot Joint**: Allows rotational movement.
- **Condyloid Joint**: Allows movement in two planes but not rotation.
- **Hinge Joint**: Allows movement in one plane (back and forth).
- **Gliding Joint**: Allows sliding movements between two flat surfaces.

3. **Focus on Neck Movement**: The neck joint that allows for the rotation of the head is specifically designed for this purpose.

4. **Identify the Joint in the Neck**: The joint that allows the head to rotate left and right is the **pivot joint**. This is because the skull has a rounded end that fits into a ring-shaped structure of the vertebrae, allowing for rotational movement.

5. **Conclusion**: Therefore, the joint of our neck that allows us to rotate our head left to right is the **pivot joint**.

**Final Answer**: Pivot joint.
