What it is and what it does
The temporal bone forms the lateral region of the skull and houses the organs of hearing. Its parts, petrous, tympanic and squamous, fuse early in the dog. The zygomatic process curves widely outward and forms the back part of the zygomatic arch; the external acoustic meatus is wide and very short, and the bony bulla is very large, round and smooth. The mandible articulates on it.
Worth remembering
The tympanic bulla and the jaw joint in the skeleton layer are parts of this bone.
Names

In the atlas lessons
The head: what you see, what is underneath (6 min):
Farther back: the parietal bone with the crest where the temporalis attaches, the temporal bone with the tympanic bulla, the occipital bone with the “bump” at the nape. The hyoid, hidden between the jaws, holds the tongue and the larynx.
