HOW MANY FACIAL BONES
14
what are the 14 facial bones
2 maxillary bones
2 Zygomatic bones
2 Lacrimal bones
2 Nasal bones
2 Inferior nasal conchae
2 Palatine bones
1 Vomer
1 Mandible
largest immovable
bones of the face.
maxillary bones
The only facial bone larger than the maxilla is
mandible.
Each maxilla assists in the formation of
three cavities of the face
mouth, basal cavity, and one orbit
four processes of maxillary bone
frontal, zygomatic, palatine, and alveolar process
A common congenital defect called a______ is an
opening between the palatine processes that is caused by incomplete
joining of the two bones.
cleft palate
articulation of maxillary (cranial)
frontal and ethmoid
articulation of maxilla(facial)
7 (zygoma, lacrimal,
nasal, palatine, inferior nasal concha, vomer, and adjacent
maxilla)
termed malar bones)
zygoma
form the
prominence of the cheeks and make up the lower outer portion of
the orbits.
zygoma
The last and largest facial bone is the lower jaw,
Mandible
delicate structure that
sometimes is fractured or “caved in” by a blow to the cheek.
zygomatic arch
is the only movable bone in the adult skull
mandible
divides each half
of the mandible into two main parts.
angle (gonion)
the area superior to each angle of mandible
ramus
area anterior to the angle is termed the
body
The single body forms from each lateral half and
unites at the anterior midline. This union is called
symphysis menti
The flat triangular area
below the symphysis, marked by two knoblike protuberances that
project forward, is called the
mental protuberance
The center of
the mental protuberance is described as the
mental point
Located on each half of the body of the mandible is the
mental
foramina.
serve as passageways for the mental
artery, the vein, and the nerve that innervates the lower lip
and chin.
mental
foramina.
The process at the anterior end of the
mandibular notch is termed the
coronoid process.
The only facial bone larger than the maxilla
mandible.
