Study Notes
- Synovial joints have an articulating capsule consisting of an outer fibrous layer and an inner synovial membrane
- Joint cavity contains lubricating synovial fluid secreted by the synovial membrane
- Articular cartilage covers bones' articulating surfaces
- Synovial membrane lines internal surfaces
- Bursae are located between skin and bony prominences to aid tendon movement
- Synovial joints classified by shapes and movements they permit: ball-and-socket, condyloid, hinge, pivot, saddle, plane
- Ball-and-socket joints have wide range of motion, including all planes and rotational movements
- Condyloid joints have limited rotational movement, with a variety of movements in different planes
- Hinge joints allow movement in one plane
- Pivot joints have cylindrical surfaces rotating in a ring
- Saddle joints have complementary concave and convex surfaces
- Plane joints permit sliding movements in the plane of the articular surfaces
- Synovial joint movements are produced by contracting muscles on either side
- Muscles contract and pull on movable ends, causing movement
- Rotation, circumduction, pronation, supination, eversion, inversion, retraction, protraction, elevation, depression are types of joint movements
- Synovial joints receive blood from articular arteries and have a rich nerve supply
- Arthritis is a disease causing inflamed, swollen, and painful joints, affecting over 50 million people in the US
- Synovial joints classified based on shape: axial uniaxial, biaxial, pivot, multiaxial, condyloid, hinge, metacarpophalangeal, radioulnar, acromioclavicular, shoulder, saddle, elbow, sternocostal, elipsoid, and wrist.
- Muscles move joints by producing movement when they contract
- Joints movements are classified as rotation, circumduction, pronation, supination, eversion, inversion, retraction, protraction, elevation, depression
- Joints have a rich nerve supply, and nerves transmit sensory impulses for proprioception
- Pain fibers are numerous in the fibrous layer and accessory ligaments
- Synovial membrane is relatively insensitive to pain.
