An ellipsoid joint, also known as a condyloid joint, is a type of synovial joint that allows for movement in two planes. It is a biaxial joint that permits angular motion.
Characteristics of Ellipsoid Joints
Here's a breakdown of the key characteristics:
- Movement: Ellipsoid joints allow movements in all angular motions. The movement of ellipsoid joints is in two plains:
- Back and front (flexion and extension).
- Side to side (abduction and adduction).
Examples of Ellipsoid Joints
Ellipsoid joints are found in several locations within the body, including:
- Knuckle joints.
- Wrist joints.
- Metacarpophalangeal joints of the fingers (where the fingers meet the hand).
- Metatarsophalangeal joints of the toes (where the toes meet the foot).
Summary
In essence, an ellipsoid joint provides stability while allowing for a wide range of motion in two planes, making it essential for various hand and foot movements.
