QuestionAnswer
glenohumeral ligaments placement one end attaches to the rim of the glenoid cavity, the other attaches to the humerus, 3 of them
transverse humeral ligaments placement runs across the humerus and goes over the intertubercle sulcus--extends between the greater and lesser tubercles of the humerus
transverse humeral ligaments function keeps biceps muscle tendon in the sulcus
coracohumeral ligament placement runs from the coracoid process to the humerus
Coracoacromial ligament placement runs from the coracoid process to the acromion
rotator cuff muscles function maintain most of the stability of the joint, hold the head of the humerus in the glenoid cavity
rotator cuff muscles location found along the superior, anterior, and posterior sides of the shoulder joint
Movement possible at the shoulder joint abduction, adduction, circumduction, extension, flexion, hyperextension, lateral rotation, and medial rotation of the arm
Movements possible at the knee joint extension, flexion, lateral rotation of leg in flexed position, slight medial rotation
anterior cruciate ligament placement runs from the posterior femur to the anterior side of the tibia
anterior cruciate ligament function becomes tighter as you extend your knee, prevents hyperextension of the knee
posterior cruciate ligament placement runs from the anteroinferior femur to the posterior side of the tibia
posterior cruciate ligament function tightens as you flex the knee, keeps the femur from sliding off the tibia
tibial (medial) collateral ligament runs from the femur to the tibia and reinforces the medial surface of the knee joint
fibular (lateral) collateral ligament runs from the femur (lateral epicondyle) to the fibula and reinforces the lateral surface of the knee joint
medial and lateral menisci placement fibrocartilage articular discs between each condyle and the proximal end of the tibia
menisci function cushion and keep bones together
unhappy triad injury #1 damage to medial collateral ligament due to a severe lateral blow
unhappy triad injury #2 torn medial menisci
unhappy triad injury #3 torn anterior cruciate ligament (weakest)
