It has the form of a four-sided pyramid, the l^ase of which is ventral. The lateral surface is mainly concealed by tlie sciuamous temi^oral, but two features are visiljle. A short tube of bone, the external acoustic process (Processus acusticus externus), protrudes from the lowest part through the notch of the squa- mous temporal. The process is directed outward, upward, and a little 3 Fig. 39.—Right Squamous Temporal Bone of New-born Foal; Medial View. Cerebral surface; 1, zygomatic process; 2, junction with parietal; 3, junction with temporal wing of sphenoid; 4, posterior process (overlaps petro-mastoid). It gives attachment to the annular cartilage of the ear. Its lumen, the external acoustic meatus (Meatus acusticus externus), conducts to the cavity of the middle ear (tympanum) in the dry skull, but is separated from it by the tympanic mem- Ijrane in the natural state. The mastoid process (Processus mastoideus) projects ventrally in tlie interval lietween the posterior process of the squamous temporal.
