No, plane joints do not allow rotation.
Understanding Plane Joints (Gliding Joints)
Plane joints, also known as gliding joints, are characterized by flat or slightly curved articulating surfaces. This structure primarily facilitates gliding or sliding movements in a single plane.
Range of Motion in Plane Joints
The movement permitted by plane joints is primarily translational. This means that bones can slide or glide across one another. Examples include:
- Intercarpal joints: Between the carpal bones in the wrist.
- Intertarsal joints: Between the tarsal bones in the ankle.
- Vertebrocostal joints: Where the ribs connect to the vertebrae.
While some limited multi-planar movement might occur, rotation is not a characteristic or intended function of plane joints. The ligaments and bony structures surrounding these joints are structured in a way that limit movement to gliding actions, not rotation.
Summary
Plane joints are designed for gliding or sliding movements, not rotation. Their structure and the surrounding ligaments restrict movement to this plane.
