 Articulations of elbow joint are;  Capitulum (lateral condyle of humerus) with the radius  Trochlea (medial condyle of humerus) with the ulna

 Ulnar Collateral Ligament(UCL)  Radial Collateral Ligament  Annular Ligament: stabilizes and encircles the head of the radius

Movement

 Superior Radioulnar: pivot joint moving in a ring formed by the ulna and annular ligament  Middle Radioulnar: shaft of bones held together by the interosseus membrane  Distal Radioulnar: pivot joint formed by the head of ulna with a notch on the radius

 Articulation of the radius and ulna with the scaphoid, lunate, and triquetral
