Gliding movements

Definition

Gliding movements are a type of joint movement where flat bone surfaces slide over one another. These movements occur in plane joints and allow for limited motion in various directions.

5 Must Know Facts For Your Next Test

1. Gliding movements primarily occur in plane (or planar) synovial joints.
2. Examples of gliding movements can be found between the carpal bones in the wrist and the tarsal bones in the ankle.
3. These movements are non-axial, meaning they do not involve rotation around an axis.
4. Gliding movements contribute to the flexibility and range of motion within joints by allowing bones to shift slightly past each other.
5. The primary function of gliding movements is to facilitate small adjustments that help maintain stability and distribute mechanical stress across multiple bones.
