THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -funny bone Usually applied to the projection, the olecranon, at the back of the elbow, which is the upper end of the ulna, one of the two forearm bones. On the inner side of this is a smaller protuberance, the medial epicondyle of the humerus-the bone of the upper arm.

Detailed explanation-2: -The olecranon (/oʊˈlɛkrənɒn/, from Greek olene ‘elbow’, and kranon ‘head’), is a large, thick, curved bony eminence of the ulna, a long bone in the forearm that projects behind the elbow. It forms the most pointed portion of the elbow and is opposite to the cubital fossa or elbow pit.

Detailed explanation-3: -The projection that forms the upper border of this notch is called the olecranon process; it articulates behind the humerus in the olecranon fossa and may be felt as the point of the elbow.

Detailed explanation-4: -Olecranon process projects upwards from the shaft of ulna. It has superior, anterior, posterior, medial and lateral surfaces. Posterior part of the superior surface of the olecranon process gives insertion to the triceps brachi and anterior part of the surface is covered by bursa [1].
