Also called the Malars or Jugals, each cheek or zygomatic bone
possesses three major processes which articulate with the bones which surround
it. The Frontal Process of the zygomatic forms the lateral margin and wall of
the eye orbit and projects superiorly to articulate with the zygomatic process
of the frontal bone. This portion of the bone separates the eye orbit from
the temporal fossa and possesses a posterior projecting edge called the
Marginal Process. The Temporal Process of the zygomatic runs lateral
and posterior toward an articulation with the zygomatic process of the
temporal bone. Together these two processes assist in forming the zygomatic arch which serves as the attachment for the masseter muscle in life, one of the primary
muscles used in mastication. The temporal muscle runs beneath the arch and is
also a primary mover of the mandible in chewing. The Maxillary
Process of the zygomatic articulates with the zygomatic portion of the
maxilla by way of the Zygo-Maxillary Suture.
The zygomatics touch, or articulate with, the following bones:
