Os temporale (Schläfenbein)

The video tutorial provides a detailed examination of the temporal bone, a bilateral bone forming part of the skull's base and lateral wall. It is divided into four parts: pas squamosa, tympanic part, styloid process, and pars petrosa. Each part's structure and function are explored, including their roles in forming the skull's lateral wall, ear canal, and connections with other bones. The tutorial also covers the zygomatic process, mastoid process, and various sutures connecting the temporal bone to adjacent bones.
