The anterior surface bears the impress of the gyri of the under surface of the temporal lobe of the cerebrum, which rests upon it; in addition, there is a distinct but shallow depression (impressio trigemini) near the apex, corresponding to the roof of the carotid canal; in this is lodged the semilunar ganglion on the sensory root of the trigeminal nerve. Lateral to the middle of the upper surface, and close to its posterior border, is the elevation (eminentia arcuata), more or less pronounced, which marks the position of the superior semicircular canal, here developed within the substance of the bone. A little Tympanic antrum, the medial â wall of which is related to the lateral semicircular canal Internal part of posterior wall of external acoustic meatus left in situ Points to the recessus epitympanicus Fenestra cochlea; Mastoid air cells. Facial nerve Facial canal laid open, displaying the facial nerve within Fig. 139. Preparation to display the position and relations of the tympanic antrum. The greater part of the posterior wall of the external acoustic meatus has been removed, leaving only a bridge of bone at its inner ex- tremity ; under this a bristle is displayed, passiug from the tympanic antrum through the iter to the cavity of the tympanum, in front of this, and in line with the angle formed by the anterior border and the squamous part, is the slit-like opening of the hiatus canalis facialis,
