Fig. 2.2 Skeletal structure of
the human skull showing the
nasal cavity and the
supporting facial bones
in between the forehead and the upper lip. It is made up of a bony section and a
cartilaginous section. The bony section is located in the superior half and contains a
pair of nasal bones sitting together side by side, separated in the middle and fused
posteriorly by the medial plates of the cheekbones ( maxilla bones ) (Fig. 2.2 ).
The cartilaginous section is located in the inferior half, consisting of flexible
cartilages in the anterior, caudal portion of the nose (Fig. 2.3 ). The cartilages are
connected to each other and to the bones by a tough fibrous membrane. At the base
