The temporal bone or squamosal is a even Os Crâne located in the area of the Tempe, on the side part of the head. It takes part as well in the formation of the vault as the base of the cranium (cranial pits average and posterior). It accommodates also the Articulation temporo-mandibulaire. It is a complex bone resulting from the meeting of three bones: the scale, the rock and the tympanal.

Inside the rock, is a cavity, the Drum of the ear sheltering the ossicles, and the vestibular body cochléo.

Relationship of temporal with the bones of craniums

The temporal bone (in red on the drawing) is articulated with:

• the parietal Os in top (in gray),
• the large wing of the sphénoïde ahead (in yellow),
• the mandible by the means of the articulation temporo-mandibulaire (in red).
• the zygomatic Os ahead with the zygomatic process (in clear gray).
