Study Notes
Joint Types and Movements
- Hinge joints permit uniaxial flexion-extension movements, functioning similarly to a door hinge.
- Saddle joints exhibit articular surfaces that resemble a saddle on a horse's back, allowing for a unique range of motion.
- The sternoclavicular joint allows for sliding movements of the bones, primarily enabling movement in multiple directions including forward, backward, and upwards.
- Ball-and-socket joints consist of a ball-shaped head of one bone fitting into a socket-like concavity of another, offering the greatest range of motion among joint types.
- Ellipsoidal joints feature an elliptical convex articular surface fitting into an elliptical concave surface, facilitating movement in two planes.
- Bicondylar joints articulate with two distinct convex surfaces engaging with two concave surfaces, enabling limited movement primarily in one plane.
