title: Nerve supply for anomalous ocular muscle in man.
abstract: Of the orbitas of 85 humans examined, the same type of anomalous ocular muscle was found in 5 orbitas from three men and a woman. The anomalous ocular muscle, which originated the belly or the proximal part of the M. levator palpebrae superioris to attach to the Sclera, Trochlea and neighbouring tissues, was identical to the M. tensor trochleae described by Budge (1859) was innervated by the Ramus superior of the N. oculomotorius. Two main branches from the R. superior of the N. oculomotorius for the M. rectus superior united to form common loop before supplying the M. levator palpebrae superioris. The loop had a few branches of which the thick one supplied the M. levator palpebrae superioris and smaller ones innervated the anomalous ocular muscle from the ventral and sometimes dorsal sides.
