The joint which allows side to side as well as forward and backward movements is called

Options

A. hinge joint
B. pivot joint
C. ball and socket joint
D. gliding joint.

Explanation

### Step-by-Step Text Solution:

1. **Understanding Joint Movements**: Joints in the human body allow different types of movements. The question asks for a joint that allows both side-to-side and forward-and-backward movements.

2. **Identifying Joint Types**:
- **Hinge Joint**: Found in the knee and elbow, this joint allows movement in one direction (like a door) but does not permit side-to-side movement.
- **Pivot Joint**: Located in the neck, this joint allows side-to-side movement but is limited in forward and backward movement.
- **Ball and Socket Joint**: This joint allows for a wide range of motion, including rotation, but primarily facilitates forward and backward movement rather than side-to-side.
- **Gliding Joint**: Found in the wrists and ankles, this joint allows for both forward and backward movements as well as side-to-side movements due to the flat surfaces of the bones that slide over each other.

3. **Conclusion**: The joint that allows both side-to-side and forward-and-backward movements is the **gliding joint**.
