Study Notes
Joint Classifications
- Synovial joints are functionally classified as diarthroses.
- An immovable joint is called a synarthrosis.
- A slightly movable joint is designated as amphiarthrosis.
- A freely movable joint is termed diarthrosis.
Joint Examples and Types
- Sutures are specific examples of synarthroses.
- Dense connective tissue in sutures corresponds to the periodontal ligament in gomphosis.
- Four major types of synarthrotic joints include sutures, synchondroses, synostoses, and gomphoses.
- Joints can be structurally categorized as synovial, bony, fibrous, or cartilaginous.
Joint Anatomy
- The location where two bones meet is referred to as an articulation.
- The periosteum is continuous with the joint capsule, enhancing joint stability.
- The meniscus channels synovial fluid flow and provides mechanical support.
Synovial Fluid Characteristics
- Synovial fluid provides nutrients, shock absorption, lubrication, and protects articular cartilages.
- Increasing osmotic pressure within the joint is not a function of synovial fluid.
Articular Cartilage Properties
- Articular cartilage surfaces are smooth and slick, composed of hyaline cartilage with a high water content.
- Articular cartilage does not secrete synovial fluid.
Joint Structure and Movement
- Synovial joints contain synovial fluid, are reinforced by accessory structures, and are covered by a capsule, but not by a serous membrane.
- Bursae are small pockets of synovial fluid that reduce friction around ligaments and tendons.
Specific Joint Types
- The first carpometacarpal joints represent saddle joints.
- The elbow is classified as a hinge joint.
- Joints between carpal bones are gliding joints.
- The shoulder joint allows for the greatest range of motion of any joint in the body.
Joint Classifications and Movements
- Rolling is not a recognized structural classification of synovial joints.
- The shoulder is an example of a ball-and-socket joint.
- Hinge joints allow only flexion and extension.
Movement Definitions
- Abduction refers to movement away from the body's longitudinal axis in the frontal plane.
