Pivot Joint

Pivot Joint: A pivot joint (also called a trochoid joint, rotary joint, or lateral ginglymus joint) is a type of synovial joint in which the cylinder of one bone fits into a corresponding cavity, allowing for rotational motion. Examples include the articulation between the first and second cervical vertebrae (c1/c2 a.k.a. atlas/axis) and the proximal radioulnar joint.

• Note: These joints primarily allow movement in one plane of motion , and usually the transverse plane . These motions can be described as rotation (ipsilateral rotation and contralateral rotation).

Examples of Hinge Joints of the Human Body:

Here is a list of the joints in the human body that are classified as "hinge joints":

1. Atlantoaxial Joint (C1-C2 Joint) : This joint is the junction of the first and second cervical vertebrae (i.e., atlas and axis). It allows the head to rotate from side to side, such as when shaking your head to indicate "no."
2. Radioulnar Joint: This joint is found near the elbow, between the head of the radius and the radial notch of the ulna. It allows the forearm to rotate, enabling movements such as turning the palm up (supination) and down (pronation).

All Synovial Joint Types:

• Ball-and-socket Joint
• Hinge Joint
• Gliding Joint
• Condyloid Joint
• Pivot Joint
• Saddle Joint
