Zygomatic arch

<h2 id="structure">Structure</h2>
<p>The zygomatic process of the temporal arises by two roots:
</p>
<ul><li>an <i>anterior</i>, directed inward in front of the <a href="/facts/Mandibular_fossa/2Jy3AQFj">mandibular fossa</a>, where it expands to form the articular tubercle.</li>
<li>a <i>posterior</i>, which runs backward above the <a href="/facts/External_acoustic_meatus/1dvynGqs">external acoustic meatus</a> and is continuous with the supramastoid crest.</li></ul>
<p>The upper border of the arch gives attachment to the <a href="/facts/Temporal_fascia/YRN1qYNN">temporal fascia</a>;<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> the lower border and medial surface give origin to the <a href="/facts/Masseter/lmcC1SbQ">masseter</a>.

<p><a href="/facts/High_cheekbones/on2Xkb0q">High cheekbones</a> 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 <a href="/facts/Facial_symmetry/AaLXoWPe">symmetrical face shape</a>, are very common in <a href="/facts/Fashion_model/MbCN8xJz">fashion models</a> and may be considered a <a href="/facts/Physical_attractiveness/Xg6bI7zy">beauty trait</a> in both males and females within Eurocentric beauty standards.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>
</p>
<h2 id="etymology">Etymology</h2>

<p>The term <i>zygomatic</i> 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 <a href="/facts/Galen/9gDqPdwl">Galen</a> (2.437, 746) in the 2nd century AD. The zygomatic arch is occasionally referred to as the <a href="/facts/Zygoma/MT8FTkKw">zygoma</a>, but this term usually refers to the zygomatic bone or occasionally the <a href="/facts/Zygomatic_process/TbQQsfWA">zygomatic process</a>.
</p>
<h2 id="other-animals">Other animals</h2>
<p>The zygomatic arch is significant in <a href="/facts/Evolutionary_biology/8tBoG55U">evolutionary biology</a>, as it is part of the structures derived from the ancestral single <a href="/facts/Temporal_fenestra/F3WRzwbM">temporal fenestra</a> of the <a href="/facts/Synapsid/uzYVtB0F">synapsid</a> ancestor of <a href="/facts/Mammal/phSwTzBo">mammals</a>.
