The masseter muscles attaches some fibres to the lateral surface of the zygomatic process. One of the zygomatic processes’ attachments to the temporal bone forms the articular tubercle – the anterior boundary of the mandibular fossa, part of the temporomandibular joint These two structures form the zygomatic arch (palpable as ‘cheek bones’). It projects anteriorly, articulating with the temporal process of the zygomatic bone. The zygomatic process arises from the lower part of the squama temporalis. The bone articulates with the sphenoid bone anteriorly, and parietal bone laterally. The lower part of the squamous bone is the site of origin of the temporalis muscle The outer facing surface of the squamous bone is convex in shape, forming part of the temporal fossa. It is flat and plate-like, located superiorly. SquamousĪlso known as the squama temporalis, this is the largest part of the temporal bone. We shall now examine the constituent parts of the temporal bone in more detail. Fig 1.1 – The constituent parts of the temporal bone.
