glenohumeral joint

between humerus head and glenoid fossa

coracohumeral ligament - extends from coracoid process to greater tubercle of humerus

rotator cuff muscles - 4 muscles encircle shoulder joint, fuses with articular capsule to stabilize joint movements

coxal joint

head of femur and acetabulum

iliofemoral, ischiofemoral and pubofemoral ligaments link femur and coxal bone

tibiofemoral joint

between tibia and femur

lateral and medial menisci - composed of fibrocartilage, absorbs shock, prevents side-to-side rocking of joint

anterior and posterior cruciate ligaments - ACL prevents forward joint displacement, PCL prevents backwards joint displacement

lateral and medial collateral ligaments - limits rotation of joint during extension movements
