Which of the following joints allows `360^(@)` movement?

Options

A. Hinge joint
B. Gliding joint
C. Ball and socket joint
D. Both B and C

Explanation

To determine which joint allows for 360-degree movement, we can analyze the different types of joints mentioned in the question.

### Step-by-Step Solution:

1. **Understanding Joint Types**:
- There are various types of joints in the human body, and each type allows for different ranges of movement.

2. **Hinge Joint**:
- A hinge joint allows movement in one direction, similar to how a door opens and closes. An example is the elbow joint, where the humerus, radius, and ulna connect. This joint does not allow for 360-degree movement.

3. **Gliding Joint**:
- A gliding joint (also known as an arthrodial joint) allows for sliding movements between flat surfaces. An example is the joints in the wrist. This joint also does not permit 360-degree movement.

4. **Ball and Socket Joint**:
- A ball and socket joint allows for rotational movement in multiple directions, including 360 degrees. Examples of this joint type are the shoulder joint (where the head of the humerus fits into the glenoid cavity) and the hip joint (where the head of the femur fits into the acetabulum).

5. **Conclusion**:
- Among the joints discussed, the ball and socket joint is the only type that allows for 360-degree movement.

### Final Answer:
The joint that allows for 360-degree movement is the **ball and socket joint**.
