The main difference between a gliding joint and a hinge joint lies in their movement capabilities. A gliding joint allows gliding movement only, while a hinge joint permits uni-directional bending or extension.
Gliding Joints vs. Hinge Joints
| Feature | Gliding Joint | Hinge Joint |
|---|---|---|
| Movement | Gliding movement only. | Uni-directional bending or extension. |
| Example | (Reference states elbow and knee, this is incorrect. Examples are the intercarpal and intertarsal joints) | Elbow, knee, interphalangeal joints. |
| Structure | (Not mentioned in Reference) | A cylindrical bone end fits into a trough-shaped surface. |
| Function | (Not mentioned in Reference) | Allows for movement along one plane. |
Detailed Explanation:
-
Gliding Joints (Plane Joints): These joints, also known as plane joints, are characterized by flat or slightly curved articular surfaces. This allows for gliding or sliding movements in one plane. Examples include the intercarpal and intertarsal joints of the wrist and ankle.
-
Hinge Joints: Hinge joints function much like a door hinge, permitting movement along a single axis. According to the reference, these joints are formed where "a cylindrical bone end fits into a trough shaped surface on another bone." This configuration enables flexion and extension, such as bending and straightening the elbow or knee. The reference correctly describes the elbow and knee as hinge joints and highlights that hinge joints "permit uni-directional bending or extension."
