The zygomatic process forms an "L" in this picture. As a comparison, this is how the skull looks with almost all of the zygomatic process removed. The zygomatic processes (aka. malar) are three processes (protrusions) from other bones of the skull which each articulate with the zygomatic bone. The three processes are: [1]
In the human skull, the zygomatic bone (from Ancient Greek: ζῠγόν, romanized: zugón, lit. 'yoke'), also called cheekbone or malar bone , is a paired irregular bone , situated at the upper and lateral part of the face and forming part of the lateral wall and floor of the orbit , of the temporal fossa and the infratemporal fossa .
Zygomatic (from Greek ζύγωμα (zygōma), "yoke") may refer to: Zygomatic arch; Zygomatic bone; Zygomatic branches of the facial nerve; Zygomaticus major muscle; Zygomaticus minor muscle; Zygomatic nerve; Zygomatic process. Zygomatic process of frontal bone; Zygomatic process of maxilla; Zygomatic process of temporal bone
In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); [1] the tendon of the temporal muscle ...
The zygomatic plate not extending backwards to the first molars is a diagnostic character of phyllotines. [45] Most thomasomyines lack a well-developed zygomatic notch. [44] The genus Rhipidomys has a narrow zygomatic plate, no zygomatic spine and only a narrow notch. [46] Thomasomys shares a narrow zygomatic plate. [47]
The zygomatic nerve is a branch of the maxillary nerve (itself a branch of the trigeminal nerve (CN V)). It arises in the pterygopalatine fossa and enters the orbit through the inferior orbital fissure before dividing into its two terminal branches: the zygomaticotemporal nerve and zygomaticofacial nerve .
The zygomatic branches of the facial nerve (malar branches) are nerves of the face. They run across the zygomatic bone to the lateral angle of the orbit . Here, they supply the orbicularis oculi muscle , and join with filaments from the lacrimal nerve and the zygomaticofacial branch of the maxillary nerve (CN V 2 ).
The zygomasseteric system (or zygomasseteric structure) in rodents is the anatomical arrangement of the masseter muscle of the jaw and the zygomatic arch of the skull. The anteroposterior or propalinal (front-to-back) motion of the rodent jaw is enabled by an extension of the zygomatic arch and the division of the masseter into a superficial, lateral and medial muscle.
