The zygomatic bone is one of two bones (sometimes called malar bones) that are responsible for the prominences of the cheeks below and to the sides of the eyes. These bones also help form the lateral walls and floors of the orbits (eye). Each bone has a temporal process, which extends down the back to join the zygomatic process of a temporal bone. Together, these processes form a zygomatic arch. The smooth prominence between the eyebrows is called the glabella.
