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.
Each maxilla assists in the formation of
three cavities of the face:
1) the mouth, (2) the nasal cavity, and
(3) one orbit.
four processes of maxilla
frontal, alveolar, zygomatic, and palatine process
projects upward along the lateral border of the nose
toward the frontal bone.
frontal
process
projects laterally
to unite with the zygoma
zygomatic process
is the inferior aspect of the body of each maxilla
alveolar process
a maxillary process that cannot be seen on forontal view of skull
palatine process
The body of each maxillary bone contains a large, air-filled cavity
known as a
maxillary sinus
solidly united at the midline to form a synarthrodial (immovable)
joint
two palatine processes

located lateral to the zygomatic process of each
maxilla.
zygoma
Each zygoma articulates with three cranial bones

frontal, sphenoid, and temporal
form the
prominence of the cheeks and make up the lower outer portion of
the orbits.
zygoma
Articulations Each zygoma articulates one facial bone
MAXILLA
Lacrimal, derived from a word meaning
tear,”
lie anteriorly on the medial side
of each orbit just posterior to the frontal process of the maxilla.
Lacrimal bones
associated with the
tear ducts.
Lacrimal bones
form the bridge of the
nose and are variable in size.
Nasal bones
Each lacrimal bone articulates with two cranial bones
frontal and ethmoid
Each lacrimal bone articulates with two facial bones
maxilla and
inferior nasal concha).
Each nasal bone articulates with two cranial bones
frontal

Each nasal bone articulates with two facial bones

two platelike, curved (or scroll-shaped)
facial bone
inferior nasal conchae
project from the lateral walls of the nasal cavity on each
side and extend medially
inferior nasal conchae
three pairs of nasal conchae
superior and
middle pairs are parts of the ethmoid bone and the inferior
pair consists of separate facial bones.
nferior nasal concha articulates with
one cranial bone
ethmoid)
inferior nasal concha articulates with with three facial bones

Vomer
bone is a thin, triangular
bone that forms the inferoposterior part of the nasal septum.
Vomer
The vomer articulates with two cranial bones
sphenoid and ethmoid
vomer articulates with four facial bones
