| zygomatic nerve | <anatomy, nerve> A branch of the maxillary nerve in the inferior orbital fissure through which it passes; it gives rise to two sensory branches, the zygomaticotemporal and zygomaticofacial, which supply the skin of the temporal and zygomatic regions and is continued as the communicating branch of the lacrimal nerve with the zygomatic nerve. Synonym: nervus zygomaticus, orbital nerve, temporomandibular nerve. (05 Mar 2000) |

| zygomaticofacial branch of zygomatic nerve | <anatomy, nerve> Penetrates zygomatic bone to supply skin of face over zygoma or cheekbone. Synonym: ramus zygomaticofacialis nervi zygomatici. (05 Mar 2000) |
| zygomaticotemporal branch of zygomatic nerve | <anatomy, nerve> Penetrates frontal process of zygomatic bone to supply skin of face lateral to orbit. Synonym: ramus zygomaticotemporalis nervi zygomatici. (05 Mar 2000) |
| zygomatic process of frontal bone | The massive projection of the frontal bone that joins the zygomatic bone to form the lateral margin of the orbit. Synonym: processus zygomaticus ossis frontalis. (05 Mar 2000) |
| zygomatic process of maxilla | The rough projection from the maxilla that articulates with the zygomatic bone. Synonym: malar process, processus zygomaticus maxillae. (05 Mar 2000) |
| zygomatic region | The region of the face outlined by the zygomatic bone; the prominence above the cheek. Synonym: regio zygomatica. (05 Mar 2000) |
| lateral surface of zygomatic bone | The lateral surface of the zygomatic bone. Synonym: facies lateralis ossis zygomatici. (05 Mar 2000) |
| frontal process of zygomatic bone | The process of the zygomatic bone which extends upward to form the lateral margin of the orbit and articulates with the frontal bone and greater wing of the sphenoid bone. Synonym: frontosphenoidal process, processus frontalis ossis zygomatici. (05 Mar 2000) |
| lesser zygomatic muscle | <anatomy, muscle> Origin, zygomatic bone posterior to zygomaticomaxillary suture; insertion, orbicularis oris of upper lip; action, draws upper lip upward and outward; nerve supply, facial. Synonym: musculus zygomaticus minor, caput zygomaticum quadrati labii superioris, lesser zygomatic muscle. (05 Mar 2000) |
| anterior auricular branches of superficial temporal artery | <anatomy, artery> Distribution, auricle, earlobe and external acoustic meatus. Synonym: rami auriculares anteriores arteriae temporalis superficialis. (05 Mar 2000) |
| anterior surface of petrous part of temporal bone | The surface of the petrous part of the temporal bone contributing to the floor of the middle cranial fossa. Synonym: facies anterior partis petrosae ossis temporalis. (05 Mar 2000) |
| anterior temporal artery | <anatomy, artery> A branch of the insular part of the middle cerebral artery distributed to the cortex of the anterior part of the temporal lobe. Synonym: arteria temporalis anterior. (05 Mar 2000) |
| apex of petrous part of temporal bone | The irregular antero-medial extremity of the petrous part on which the anterior end of the carotid canal opens. Synonym: apex partis petrosae ossis temporalis. (05 Mar 2000) |
| articular eminence of temporal bone | Articular eminence of the temporal bone which bounds the mandibular fossa anteriorly; it forms the anterior root of the zygomatic process; it is enclosed by the articular capsule of the temporomandibular joint with the articular fossa; the head of the mandible (and intervening articular disc) move onto the articular tubercle to allow full depression of mandible (opening of mouth). Synonym: tuberculum articulare ossis temporalis, articular eminence of temporal bone, eminentia articularis ossis temporalis, tuber zygomaticum. (05 Mar 2000) |
| articular fossa of temporal bone | A deep hollow in the squamous portion of the temporal bone at the root of the zygoma, in which rests the condyle of the mandible. Synonym: cavitas glenoidalis, fossa mandibularis, articular fossa of temporal bone, glenoid cavity, glenoid fossa, glenoid surface. (05 Mar 2000) |
