Gliding joints move when the surfaces of bones slide over one another in a linear fashion. This movement is also referred to as gliding.
Understanding Gliding Movement
Gliding movements occur when one bone surface slides or moves over another without any angular or rotary movement. This allows for a small amount of movement in multiple directions.
- Definition: According to the provided video reference, gliding occurs when the surfaces of bones move over one another in a linear fashion.
- Characteristics:
- Surfaces of bones slide over each other.
- Movement is linear.
- Minimal angular or rotary movement.
Examples of Gliding Joints
Gliding joints are commonly found in the following locations:
- Intercarpal and Intertarsal Joints: These joints are located in the wrist (carpals) and ankle (tarsals) and allow for movements like waving your hand or flexing your foot.
- Vertebrocostal Joints: These are the joints between the vertebrae and ribs.
- Sacroiliac Joints: These joints are located in the pelvis.
Functional Aspects
Gliding joints provide the following functional benefits:
- Flexibility: Allows for slight movements.
- Support: Provides stability by distributing forces across multiple bones.
- Shock Absorption: Gliding motions help in absorbing shocks, especially in the wrist and ankle.
