The principal elbow flexors located on the anterior side of the humerus are : biceps brachii, brachialis and brachioradialis.
Functional anatomy of the Elbow joint
The elbow joint is formed by three bones, namely the humerus, radius, and ulna which are interconnected to form the elbow joint.
1) Humerus
The humerus is a long bone. The part that connects with the shoulder to form the head of the joint is called the humeral head. The humeral head and glenoid cavity of the scapula unite to form the glenohumeral joint. At the humeral head there is a bulge called the major tubercle and the minus tubercle, below the humeral head there is an indentation called the humeral column. On the lower side there are the lateral humeral epicondyle and the medial humeral epicondyle. Besides that, it also has indentations, namely the coronoid fossa (front) and olecrani fossa (back).
2) Radial bone
On the proximal extremity it consists of the radial head and the fovea articularis which are connected to the circum ferentia articularis.
Medial is the transition between the neck of the radii and the trunk, there is the radial tuberosity. The trunk is more or less triangular in cross section with a medial direction consisting of the interosseous margin, the anterior surface, the anterior margin, the lateral surface, and the posterior margin which separate the lateral and posterior surfaces.
The lateral surface of the corpus radii approximately in the middle third shows a difference, namely an area that becomes roughened is called the pranotaria tuberosity.
3) Ulna bone
The proximal end is angular, curved, called the olecranon, with a rough surface. In front there is the trochealis notch up to the coronoid process. incisura radialis lies laterally and is jointed with the circum ferentia of the radii head. The tuberosity of the ulnae lies at the transition to the body of the ulnae. Laterally there is the supinator crest which extends inferiorly to the notch radialis
