| marginal tubercle of zygomatic bone | A prominence on the temporal border of the zygomatic bone to which the temporal fascia is attached. Synonym: tuberculum marginale ossis zygomatici, marginal tubercle. (05 Mar 2000) |
| greater zygomatic muscle | <anatomy, muscle> Origin, zygomatic bone anterior to temporozygomatic suture; insertion, muscles at angle of mouth; action, draws upper lip upward and laterally; nerve supply, facial. Synonym: musculus zygomaticus major, greater zygomatic muscle, musculus zygomaticus. (05 Mar 2000) |
| communicating branch of lacrimal nerve with zygomatic nerve | <anatomy, nerve> Nerve branch by which postsynaptic parasympathetic (secretomotor) fibres from the pterygopalatine ganglion are transferred from the zygomatic nerve to the lacrimal nerve (heretofore purely sensory) for distribution to the lacrimal gland. Synonym: ramus communicans nervi lacrimalis cum nervo zygomatico. (05 Mar 2000) |
| orbital eminence of zygomatic bone | A small elevation on the orbital surface of the zygomatic bone, just within the orbital margin, about 1 cm below the zygomaticofrontal suture; it gives attachment to the lateral check ligament, the lateral palpebral ligament, and the suspensory ligament of the eyeball. Synonym: eminentia orbitalis ossis zygomatici, orbital eminence of zygomatic bone, Whitnall's tubercle. (05 Mar 2000) |

| zygomatic | <anatomy> Of, pertaining to, or in the region of, the zygoma. Zygomatic arch, the arch of bone beneath the orbit, formed in most mammals by the union of the malar, or jugal, with the zygomatic process of the temporal bone. In the lower vertebrates other bones may help to form it, and there may be two arches on each side of the skull, as in some reptiles. Zygomatic process, a process of the temporal or squamosal bone helping to form the zygomatic arch. Origin: Cf. F. Zygomatique. Source: Websters Dictionary (01 Mar 1998) |
| zygomatic arch | The arch formed by the temporal process of the zygomatic bone that joins the zygomatic process of the temporal bone. Synonym: arcus zygomaticus, cheek bone, malar arch, zygoma. (05 Mar 2000) |
| zygomatic bone | A quadrilateral bone which forms the prominence of the cheek; it articulates with the frontal, sphenoid, temporal, and maxillary bone. Synonym: os zygomaticum, cheek bone, jugal bone, mala, malar bone, os malare, yoke bone, zygoma. (05 Mar 2000) |
| zygomatic border of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
| zygomatic branch of facial nerve | Branches of facial nerve crossing upper cheek to supply orbicularis oculi muscle. Synonym: rami zygomatici nervi facialis. (05 Mar 2000) |
| zygomatic diameter | The extreme breadth of the skull at the zygomatic arches. (05 Mar 2000) |
| zygomatic fossa | The cavity on the side of the skull bounded laterally by the zygomatic arch and ramus of the mandible, medially by the lateral pterygoid plate, anteriorly by the zygomatic process of the maxilla, posteriorly by the articular tubercle of the temporal bone and the posterior border of the lateral pterygoid plate, and above by the squama of the temporal bone and the infratemporal crest on the greater wing of the sphenoid bone. Synonym: fossa infratemporalis, zygomatic fossa. (05 Mar 2000) |
| zygomatic fractures | Fractures of the zygoma. (12 Dec 1998) |
| zygomatic margin of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
