Temporal bone

Template:Infobox Bone

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

The temporal bones are situated at the sides and base of the skull.

The temporal bone supports that part of the face known as the temple.

Each consists of five parts:

• Squama temporalis
• Mastoid portion
• Petrous portion
• Tympanic part
• Styloid process (temporal)

The structure of the squama is like that of the other cranial bones: the mastoid portion is spongy, and the petrous portion dense and hard.
