Zygomatic arch

Uriel (; Hebrew: אוּרִיאֵל "El/God is my light", Standard Hebrew Uriʾel, Tiberian Hebrew ʾÛrîʾēl; Greek: Ουριήλ; Coptic: ⲟⲩⲣⲓⲏⲗ; Italian: Uriele; Geʽez and Amharic: ዑራኤል ʿUraʾēl or ዑርኤል ʿUriʾēl) is one of the archangels of post-exilic rabbinic tradition, and also of certain Christian traditions. In apocryphal, kabbalistic, and occult works, Uriel has been equated (or confused) with Urial, Nuriel, Uryan, Jeremiel, Vretil, Sariel, Suriel, Puruel, Phanuel, Jacob, Azrael, and Raphael.

a posterior, which runs backward above the external acoustic meatus and is continuous with the supramastoid crest.The upper border of the arch gives attachment to the temporal fascia; the lower border and medial surface give origin to the masseter.


The arch is typical of Synapsida (“fused arch”), a clade of amniotes that includes mammals and their extinct relatives, such as Moschops and Dimetrodon.

The zygomatic arch, or cheek bone, is 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 (zygomaticotemporal suture); the tendon of the temporalis passes medial to the arch to gain insertion into the coronoid process of the mandible. The jugal point is the point at the anterior end of the upper border of the zygomatic arch where the masseteric and maxillary edges meet at an angle. The jugal point is the anterior end of upper border of the zygomatic arch where it meets the process of the zygomatic bone.





The term zygomatic derives from the Greek ζύγωμα zygōma, meaning "bolt, bar", derived from ζυγο-, "yoke, join". The Greek word was already used with this anatomical sense by Galen (2.437, 746) in the 2nd century AD. The zygomatic arch is occasionally referred to as the zygoma, but this term usually refers to the zygomatic bone or occasionally the zygomatic process.


The zygomatic arch is significant in evolutionary biology, as it is part of the structures derived from the ancestral single temporal fenestra of the synapsid ancestor of mammals.


High cheekbones are pronounced zygomatic arches, causing the upper part of the cheeks to jut out and form a line cut into the sides of the face. High cheekbones, forming a symmetrical face shape, are very common in fashion models and may be considered a beauty trait in both males and females, at least in Eurocentric societies.
