Study Notes
Movements at Synovial Joints
-
Movements are described by the plane or direction of movement, and the relationship between structures.
-
Planes of movement include:
- Monaxial—one plane (e.g., elbow)
- Biaxial—two planes (e.g., wrist)
- Triaxial—three planes (e.g., shoulder)
-
Types of movement at synovial joints include:
- Gliding
- Angular movement
- Flexion: Decrease angle
- Extension: Increase angle
- Hyperextension: Extension past anatomical position
- Abduction: Movement away from longitudinal axis
- Adduction: Movement toward longitudinal axis
- Circumduction: Complete circular movement without rotation
- Rotational movement
- Rotation relative to anatomical position (e.g., head rotation)
- Limb rotation relative to longitudinal axis
- Medial rotation (internal)
- Lateral rotation (external)
- Special movements
- Inversion: Twisting sole of foot medially
- Eversion: Twisting sole of foot laterally
- Dorsiflexion: Ankle flexion (lifting toes)
- Plantar flexion: Ankle extension (pointing toes)
- Opposition: Movement of thumb toward palm or other fingers
- Reposition: Opposite of opposition
- Protraction: Forward movement in horizontal plane
- Retraction: Opposite of protraction (pulling back)
- Depression: Moving a structure inferiorly (down)
- Elevation: Moving a structure superiorly (up)
- Lateral flexion: Bending vertebral column to the side
Classification of Synovial Joints
- Plane (gliding): Flattened or slightly curved surfaces; limited motion.
- Hinge: Angular motion in a single plane.
- Condylar (ellipsoid): Oval articular face within a depression; motion in two planes.
- Saddle: Articular faces fit together like a rider in a saddle, biaxial.
- Pivot: Rotation only, monaxial.
- Ball-and-socket: Round head in a cup-shaped depression; triaxial.
