Abstract

This study was carried out to investigate the branches and distribution of Nervus ophthalmicus of the Korean native goat. The observation was made by dissection of embalmed cadavers of ten Korean native goats. The results were as follows; 1. N. ophthalmicus arised from the trigeminal nerve in a common trunk with the maxillary nerve. 2. At the exit of the foramen orbitorotundum the N. ophthalmicus gave off Ramus zygomaticotemporalis, N. frontalis, Ramus sinuum frontalium and N. nasociliaris. 3. Ramus zygomaticotemporalis, after giving off N. lacrimalis, left the orbital cavity and gave off Rami cornuales which were distributed the caudolateral part of the base of the horn. 4. After giving off N. ciliaris longus and Ramus communicans cum ganglio ciliari, N. nasociliaris divided into N. ethmoidalis and N. infratrochlearis which gave off Rami cornuales.
