KIN-10 Lecture Notes - Lecture 32: Synovial Joint, Temporomandibular Joint, Shoulder Joint
Document Summary
Many synovial joints also contain accessory ligaments called extrascapular ligaments and intracapsular ligaments. Extracapsular ligaments of the knee intracapsular ligaments. Lie outside the articular capsule, such as the fibular and tibial collateral ligaments. Occur within the articular capsule but are excluded from the synovial cavity by. Ex: folds of the synovial membrane the anterior and posterior cruciate ligaments of the knee joint. Few synovial joints in the body contain these. Fibrocartilage structures not covered by synovial membrane that divide the synovial cavity into two small cavities. Separate movement can occur in the two cavities, such as those of the temporomandibular joint (tmj) Crescent shaped discs that are prominent features of the knee joint. During development, the menisci are sandwiched between the fibrous membrane and synovial membrane and bind strongly to the inside of the fibrous membrane. As the joint becomes functional, the synovial membrane is worn off the surface wherever the meniscus experiences considerable friction.
