Types of Joints
There are several types of joints, each allowing different ranges of motion:
- Fixed Joints: These joints do not move at all, such as the sutures in the skull.
- Hinge Joints: Allow movement in one direction, like the elbow and knee.
- Ball-and-Socket Joints: Enable rotational movement, like the shoulder and hip joints.
- Pivot Joints: Allow for rotational movement around a single axis, such as the joint between the first and second vertebrae in the neck.
- Gliding Joints: Permit sliding movements, like those in the wrists and ankles.

Examples of Pivotal Joints:
- Neck: The joint between the first and second cervical vertebrae (the atlas and axis) allows you to turn your head from side to side.
- Forearm: The joint between the radius and ulna enables the rotation of the forearm, allowing movements like turning the palm up and down.
