Function

The Musculus brachialis pulls, like the Bizeps, the lower arm upward, bends thus the arm in the elbow (inflection), particularly with proniertem lower arm (palm down). It is even stronger than the Bizeps. That is not only because of the mass of this muscle, but also to it that he pulls away only over a joint, the Ellenbeuge, and not like the Bizeps also over the shoulder joint. Thus it can transfer its Kraft better. If a heavy load to lift is carries out the Brachialis the chief work.

Antagonist is the Musculus triceps brachii the same arm.

Normally the Brachialis at the internal, ends stronger lower arm bone, to the inch. Occasionally it increased in addition, at the smaller, weaker spoke. It is however not less loadable then, because inch and spoke are by firm fraying (Membrana interossea connected and all loads keep common.
