A common example of a synovial gliding joint is the intercarpal joints in the wrist. These joints allow bones to glide against each other, facilitating movements like bending and rotating the hand.
Synovial Gliding Joints Explained
Synovial gliding joints, also known as plane joints or arthrodial joints, are characterized by their flat or slightly curved articulating surfaces. This structure permits primarily gliding or sliding movements in one or two planes. These movements are generally limited in range due to tight ligaments and joint capsules.
Here's a breakdown of key characteristics:
- Structure: Flat or slightly curved articulating surfaces.
- Movement: Primarily gliding or sliding in one or two planes.
- Range of Motion: Limited due to tight ligaments and joint capsules.
- Other Names: Plane joint, Arthrodial Joint
Examples of Synovial Gliding Joints
Besides the intercarpal joints, other examples include:
- Intertarsal Joints: Located in the ankle and foot, allowing for inversion and eversion.
- Facet Joints (Vertebral Column): Situated between the articular processes of vertebrae, enabling flexion, extension, and rotation of the spine.
- Sternoclavicular Joint: Where the sternum and clavicle meet, allowing for a limited range of motion of the shoulder.
Function of Synovial Gliding Joints
The primary function of gliding joints is to provide stability and facilitate limited movement between bones. This type of joint is crucial in allowing the wrist and ankle to perform complex movements necessary for daily activities. While the range of motion at a single gliding joint is small, the cumulative effect of several gliding joints working together contributes significantly to overall movement.
