In this pdf-note, we will learn about the structure of the temporal bone (os temporale). It contains the organs of hearing and balance, and many blood vessels and nerves pass through it. Temporal bone (os temporale) There are several parts of the temporal bone: Petrous part (pars petrosa) Petrous part (pars petrosa) Tympanic part (pars tympanica) Outer surface. (Os Temporale) The temporal bones are situated at the sides and base of the skull. Each consists of five parts, viz., the squama, the petrous, mastoid, and tympanic parts, and the styloid process. The Squama (squama temporalis). —The squama forms the anterior and upper part of the bone, and is scale-like, thin, and translucent. The petrous part (also called the pyramid) is the part of the temporal bone which houses the inner ear. It is located in the base of the skull between the sphenoid and occipital bones.
