It is divisible into a shaft, and two extremities. The Upper Extremity, the strongest part of the bone, presents for examinationtwo large curved processes, the Olecranon process, and the Coronoid process; andtwo concave articular cavities, the greater and lesser Sigmoid cavities. The Olecranon Process (cokevr), elhoiv; Kpdvov, head) is a large, thick, curvedeminence, situated at the upper and back part of the ulna. It rises somewhathigher than the coronoid, is curved forwards at the summit so as to present a pro-minent tip, its base being contracted where it joins the shaft.
