36. The Zygomatic bone is the cheekbone that articulates with maxilla, temporal, sphenoid and frontal bones of the body. They are responsible for the prominant cheeks and as well as prominence of the sides of the eyes. It also inserts the masseter muscle. There are two surfaces: malar and a temporal surface. The convex malar surface is perforated by a small aperture called Zygmaticofacial foramen at its center. The temporal surface is concave and articulates with the maxilla.
Option A.
37. The paranasal sinuses are air filled sacs located within the skull bones and nose. The maxillary, frontal, sphenoid, and ethmoid sinuses are the four paranasal sinuses present. All these sinuses finally drain into the nasal cavity. They increase the resonance of voice and lighten the skull, and provide warmth and humidify inspired air.
