Condyloid Joint | Condyloid Joint Example | Condyloid Joint Motion and Movement | Synovial Joint Notes for Biology Class
In a condyloid joint or ellipsoidal joint (a type of synovial joint), the convex oval-shaped projection of one bone fits into the oval-shaped depression of another bone.
A condyloid joint is biaxial because the movement it permits is around two axes
- Flexion
- Extension
- Abduction–Adduction.
Examples of condyloid joints are
1.Wrist Joint
2. Metacarpophalangeal joints for the second through fifth digits
3. Metatarsophalangeal joints
4. Atlanto-occipital joints
These are also called ellipsoid joints. The oval-shaped condyle of one bone fits into the elliptical cavity of the other bone. These joints allow biaxial movements—i.e., forward and backward, or from side to side, but not rotation. Radiocarpal joint and Metacarpo-phalangeal joint are examples of condyloid joints.
An example of an Ellipsoid joint is the wrist; it functions similarly to the ball and socket joint except is unable to rotate 360 degrees; it prohibits axial rotation.
