The membrane at the end of the canal is called the membranatympani, or membrane of the drum. It is a fibrous membranecovered with very sensitive skin on the outer surface, and mucousmembrane within (Fig. 192). The middle ear is the tympanum, or drum. It consists of a smallcavity in the petrous bone, on the inner side of the membrane of thedrum. Its height is barely half an inch, and the other measurementsare smaller still. It cont
