Front armlever

The front armlever is, at the man, the part of the upper limb ranging between the elbow and the Poignet.

Anatomy

Skeleton

The front armlever consists of two Os: the Ulna (in the past ulna) and the Radius. The articulation of the elbow is done mainly with the ulna, while the articulation of the Poignet (with the carpus) is done mainly with the radius. In addition, these two bones move one compared to the other in the movements of Pronosupination; schematically, in fact the radius turns around the ulna.

Musculature

The front armlever comprises 20 Muscle S, distributed in 3 cabins (former, posterior, and side). These muscles allow the majority of the movements of the wrist (adduction/abduction, inflection/extension) and of the Doigts (inflection/extension). It also contains the muscles of the pronosupination, except for the Muscle biceps brachial.

Vascularization

In the principal front armlever the Artère S is the arteries ulnar and radial.

Innervation

Principal Nerve S: the ulnar Nerve, the median Nerve, the radial Nerve and the cutaneous Nerve médial of the front armlever.
