    Description / Table of Contents: Résumé A partir de l'étude de 546 membres supérieurs (273 cadavres) nous avons trouvé 75 cas (chez 58 cadavres) de chef surnuméraire de muscle biceps brachial (21.3%). Nous en avons étudié la forme, le trajet, la taille et les insertions ainsi que l'organisation des divisions du nerf musculo-cutané. Dans de nombreux cas le chef surnuméraire provient soit de l'humérus où il s'insère entre le m. coraco-brachial et la partie proximale du muscle brachial soit/et du septum intermusculaire médial. Dans quelques cas un chef surnuméraire a été observé à partir du tendon du m. grand pectoral ou du m. deltoïde ou encore de la capsule articulaire, voire du tubercule majeur. II rejoint habituellement le chef commun du m. biceps brachial ou son aponévrose. Parfois la jonction se fait sur l'un ou l'autre des deux corps musculaire. L'étude du n. musculo-cutané montre une anastomose avec le nerf médian dans 43 des 75 membres concernés (57.3%). Cette branche anastomotique va du n. musculo-cutané au nerf médian dans 24 cas et du n. médian au n. musculo-cutané dans 12 cas, elle va dans les deux directions dans 5 cas; dans les 2 cas restant le modèle d'anastomose est variable. Parfois une branche du n. musculo-cutané entoure le chef surnuméraire et fusionne ensuite avec le tronc du nerf. La présence d'un chef surnuméraire semble donc modifier le trajet et les connexions du nerf musculo-cutané.
    Notes: Summary Out of 546 upper limbs (273 cadavers), supernumerary heads of the biceps brachii were found in 75 limbs (13.7%) of 58 cadavers (21.3%). The form, origin, and insertion of the supernumerary heads, and branching pattern of the musculocutaneus nerve were studied. In addition, the dimensions of the heads were measured. In many cases, the supernumerary head arose from the humerus, between the insertion of the coracobrachialis and the upper part of the origin of the brachialis, and/or from the medial intermuscular septum. In a few cases, a supernumerary head arose from the tendon of the pectoralis major or the deltoid, or from the articular capsule, or from the crest of the greater tubercle. The supernumerary heads typically joined the common belly, or the aponeurosis of the biceps brachii. Some heads joined the belly of the long head or that of the short head. In the examination of the branching pattern of the musculocutaneus nerve, communication between the musculocutaneus nerve and the median nerve was found in 43 out of the 75 limbs (57.3%). The communicating branch ran from the musculocutaneus nerve to the median nerve in 24, from the median nerve to the musculocutaneus nerve in 12, in both directions in 5, or in another type of pattern in 2 out of 43 limbs. Sometimes a branch of the musculocutaneus nerve ran around a supernumerary head and then fused with the present trunk. The presence of a supernumerary head seemed to affect the course and branching of the musculocutaneus nerve.

    Notes: Abstract The expression of S-100 protein was analyzed in the human fetal inner ear using immunohistochemical methods. In the 11-week-old human fetus, the cochlea was almost negative for S-100 protein, whereas in the 14- and 15-week-old fetuses, the spiral ligament, Reissner's membrane and spiral limbus were positive for the protein. These results suggest that S-100 protein may be a reliable marker for determining functional maturation of the fetal cochlea and the inner ear. In the l l-, 14- and 15-week fetuses, the epithelial cells of the endolymphatic sac were labelled with S-100 protein. These findings demonstrate that the endolymphatic sac, spiral limbus and spiral ligament in the fetal inner ear have a high activity of S-100 protein, with this presence possibly related to fluid and ion transport of endolymph.

    Notes: Summary The expression of laminin was analyzed in the human fetal inner ear using immunohistochemical methods. In the 11-week-old human fetus, the presence of laminin was found in the basement membrane of the immature cochlea, endolymphatic sac and vestibular end organs. The reaction of the basement membrane of the endolymphatic sac was strong in the 15-week-old human fetus. A laminin reaction was seen in the cochlea, Reissner's membrane, epithelial cells of the limbus spiralis, the basilar membrane and the stria vascularis. In particular, the capillaries and basement membrane of the stria vascularis were strongly positive. These results suggest that laminin may be an essential component in the development of the inner ear and may possibly be related to filtration of the endolymph.
