Temporal Bone (Temporalis)
The major structure of the temporal region is the temporal bone. The term "temporal" region of the skull and the "temporal" bone
specifically comes from the Latin word tempus or time. Grey hairs first appear in the temporal area in males, thus a mark of age or
time. The main functions of the temporal bone are hearing and balance. The temporal bones are a pair of bilateral, symmetrical
bones that constitute a large portion of the lateral wall and base of the skull . They are highly irregular bones with extensive
muscular attachments and articulations with surrounding bones.
There are a number of openings and canals in the temporal bone through which structures enter and exit the cranial cavity. The
temporal bone also houses the structures forming the middle and inner ear. Temporal bones ensure that the cranium is properly
supported and protect the important structures there.
