| Question | Answer |
|---|---|
| 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) |
