Temporal bone

January 2017


Definition

Located near the temple, the temporal bone is part of the cranial vault and the middle and posterior cranial pits. Like many bones of the skull, the temporal bone is formed by the fusion of the tympanic, squamosal, and petrous bones, a fusion that occurs in humans during adolescence. From this point onwards, the temporal bone is described as being composed of three distinct parts: the squama, petromastoid part, and tympanic ring. Note that the tympanic ring contains the eardrum, which is involved in the transmission of sound.
