title: [Anatomic contribution to the study on the variety of fibrous formations of the arm in humans].
abstract: The authors have examined an anatomical preparation of a human upper limb preserved in the Anatomical Museum in Bologna. The specimen was formed by bone, fibrous formations, musculus biceps brachii and musculus coracobrachialis. The soft parts were kept in situ and dried by mummification. The humerus showed abnormalities at its proximal extremity (Fig. 1) and the muscles displayed fibrous varieties: a) a fibrous sheet (Fig. 1, 2) connected the caput brevis of the musculus biceps brachii to the articular capsule of the shoulder joint; b) an aponevrosis (Fig. 1, 3) connected the musculus coracobrachialis to the same articular capsule and the humerus. These observations were discussed from an evolutionary and functional point of view.
