Document Summary
Briefly describe the 2 layers of an articular capsule? outer fibrous membrane and inner synovial membrane. Describe the important functions of synovial fluid? reduces friction by lubricating the joint,absorbing shocks, and supplying oxygen and nutrients to and removing carbon dioxide and metabolic wastes from the chondrocytes within articular cartilage. What function does a bursa serve? alleviate friction in some joints. What function does a tendon sheath serve? reduce friction at joints. What are the 4 types of motion possible at diarthodial joints? gliding, angular, rotations, and special. Briefly describe the term flexion. decrease the angle in articulating joints. Briefly describe the term extension. increase the angle in articulating joints. In which plane does flexion usually occur? sagittal. In which plane does extension usually occur? sagittal. Give an example of flexion. head toward chest, palm towards forearm. Give an example of extension. head back, backbend,
