Zygomatic arch Totally Explained

Everything about The Zygomatic Arch totally explained

The zygomatic arch is formed by the zygomatic process of 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 (the side of the cheekbone), the two being united by an oblique suture; the tendon of the Temporalis passes medial to the arch to gain insertion into the coronoid process of the mandible.
The zygomatic process of the temporal arises by two roots:

an anterior, directed inward in front of the mandibular fossa, where it expands to form the articular tubercle.
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.
