Processus zygomaticus
- Related terms: Zygomatic process of temporal bone
Definition
The zygomatic process of the temporal bone is an elongated, lateral bony protrusion of the squamous part of the temporal bone, extending ventrally and cranially from the temporal region of the cranium.
It articulates with the temporal process of the zygomatic bone to form the zygomatic arch, a bone structure essential for the lateral delimitation of the temporal fossa and the passage of the temporalis muscle. The zygomatic process also contributes to the formation of the mandibular fossa, the articular surface for the mandibular condyle in the temporomandibular joint.
Variation:
In carnivores, it is very robust.
