The cavity of the temporal bone

The temporal bones protrude here not only for the mammillary processes [processus mastoideus] but also into the inner space [fossa cranalis media] (between T and i in fig. 6, or Z in fig. 8, Bk. 7) of the head to make a large empty place [cavitas tympanica] where the organ of hearing might have a sufficient space to dilate its nerve, form its sinuses, and locate its special ossicles [ossicula auditoria]. In the second chapter after this I will explain what sort of ossicles these are. Now I shall complete my account of the temporal bone, one of whose processes I have now described: from the shape of the teat of a cow’s udder the Greeks call it mastoeidh/j, mastoid; we call it mammillary [processus mastoideus]. It is larger than could fitly be compared to the delicate nipples of women. 103
