The present work making histological studies of certain part of medulla
oblongata on seven one humped camel ( Camelus Dromedarius ) of different
ages and sexes. The location of Vagus X, accessory XI and hypoglossal XII
nerve nuclei. The hypoglossal nerve XII nucleus consist of two nuclei dorsal
greater and ventral smaller and the dorsal nuclei observed. Connected with
dorsal motor vagal nucleus X by specific arch of fiber in many sections and
another observation the root fiber of hypoglossal nucleus XII pass along the
lateral border of inferior olivary nucleus and some sections the root fiber
penetrate lateral part of inferior olivary nucleus.
