On either side of this sulcus is an elevation, the medial eminence, bounded laterally by a sulcus, the sulcus limitans.[1] In the superior part of the fossa the medial eminence has a width equal to that of the corresponding half of the fossa, but opposite the superior fovea it forms an elongated swelling, the colliculus facialis, which overlies the nucleus of the abducent nerve, and is, in part at least, produced by the internal genu of the facial nerve.
