The temporal bone is a complex cranial bone that constitutes a large portion of the lateral wall and base of the skull. 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.
This video tutorial will provide you with an overview of the temporal bone.
