Study Notes
Classification of Synovial Joints
- Synovial joints are categorized by the shape of the adjoining articular surfaces.
Plane Joint
- Also known as a gliding joint.
- Examples include intervertebral joints; allows slight gliding motion between two flat bone surfaces of equal size.
Saddle Joint
- Found in the carpometacarpal joint of the thumb.
- Features two saddle-shaped articulating surfaces positioned at right angles to each other for complementary articulation.
Hinge Joint
- Examples include the cubital (elbow) and knee joints.
- Functions as an uniaxial joint where a convex cylinder of one bone fits into a matching concave surface of another.
Pivot Joint
- Includes the proximal radioulnar joint and the atlantoaxial joint.
- A uniaxial joint that allows rotation around a single axis.
Ball-and-Socket Joint
- Examples are the glenohumeral joint (shoulder) and hip joint.
- Consists of a spherical head from one bone fitting into the socket of another bone.
Ellipsoid Joint
- Example is the atlantooccipital joint located in the neck area.
- Also referred to as a condyloid joint, it is a modified ball-and-socket joint, allowing for movement in two planes.
