Health Sciences 2300A/B Lecture Notes - Lecture 5: Ulnar Collateral Ligament Of Elbow Joint, Joint Capsule, Synovial Joint
Document Summary
Muscles are able to both move and support joints (ankle bone example) 2 methods to classify ligaments (funcional and structural) Very controlled/ limited movement; takes a lot of energy to move. Example: joint between ribs and sternum: diarthroses. Tight , no joint cavity, no hyaline (no need to reduce fricion) Examples: sutures, sydesmoses (ligaments holding two bones together, for example from radius notch to ulna), gomphoses (skull, interosseous membranes, teeth) Ariculaion bones are united with carilage instead of ibers. Synchondroses (direct hyaline linkage, such as between ribs and sternum), symphyses (could be ibrocarilage (a disc) in between vertebrae but it does contain hyaline carilage, not direct linked) Have joint cavity, ibrous and carilaginous material. Most dominant joint in the body; designed for movement. Very few synovial joints have all the components labelled but they must have the joint cavity. The more moveable, the more features it has.
