a. Zygomatic Bones. These bones (right and left) form the lower and outer
edges of each orbit. They also form that part of each zygomatic arch nearest the eye
(the prominent part of the cheekbone). The zygomatic bone and the zygomatic process
of the temporal bone form the zygomatic arch. The anterior edge of the zygomatic bone
joins the maxilla.
b. Nasal Bones. These bones (right and left) are long, thin pieces of bone that
form the upper part of the bridge of the nose. The lower portion or anterior (front) part
of the nasal septum is composed of cartilage.
c. Lacrimal Bones. These bones (right and left) form small parts of the medial
walls of the orbits. They transmit the nasolacrimal duct from the eye to the nose or the
d. Inferior Nasal Conchae. These bones (right and left) are scroll-like bones
lying horizontally along the lateral walls of the nasal cavity (nose), being the skeletal
portion of the inferior nasal conchae. The bony elements of the middle and superior
conchae are extensions of the lateral parts of the ethmoid bones.
e. Palatine Bones. These bones (right and left) join in the midline to form the
posterior part of the hard palate. They also form part of the floor and lateral walls of the
nasal cavity and part of the floor of the orbits.
f. Vomer. It forms the inferior (lower) and posterior part of the nasal septum. It
is the vertical partition separating the right and left nasal cavities.
The jaws are the bony parts of the face that hold the teeth and form the
framework of the mouth. They are paired bones and form the middle of the face. The
upper jaw is called the maxilla and the lower jaw is called the mandible. Any
malformations or malfunctioning of the jaws, whether from accidental or natural causes,
may have serious consequences for the individual's health and happiness. The
sociopsychological importance of the face cannot be overemphasized.
