Facial Bones
14 bones make up the face.
12 of these bones are pairs
Maxilla (right and left)
The two maxilla bones fuse to form the
upper jaw.
The maxilla holds the upper teeth
Part of the maxilla forms the anterior part of
the palate of the mouth
All facial bones except the mandible join at
the maxilla
Palatine Bones
Paired bones that
lie posterior to the
palatine processes
of the maxillae.
Form the posterior
part of the palate.
Failure for these
bones to fuse result
in a cleft palate.
Zygomatic Bones
Commonly referred to as the cheek bones.
They form the lateral portion of the orbits
(eye sockets).
They fuse with the zygomatic process of
the temporal bone.
Zygomatic
Bones
Lacrimal Bones
Finger-nail sized bones
that form part of the
medial walls of the
orbit.
Each lacrimal bone
has a small groove so
that tears can drain
into the nasal cavity.
Nasal Bones
Two, small
rectangular bones
that form the
bridge of the nose.
The anterior part of
the nose is made
up of cartilage.
Mandible
The lower jaw
The largest and strongest bone of the face
Forms the only movable joint in the skull
Articulates with the temporal bones on each
side of the face
The horizontal part forms the chin
The lower teeth are found in alveoli (sockets)
Vomer Bone
The single bone in the inferior median line
of the nasal cavity
Forms the lowest portion of the nasal
septum
“vomer’ means plow.
Inferior Conchae
Thin curved bones projecting from the
lateral walls of the nasal cavity
Nasal
bone
Vomer bone
Inferior concha bones
Sinus Cavities (4)
 Hollow portions of bones surrounding the
nasal cavity
Functions of nasal sinuses
– Lighten the skull
– Give resonance and tone to your voice
Hyoid Bone
Not really a facial bone.
It is located superior to the larynx.
The only bone in the
body that does not
articulate with another
bone.
Serves as an
attachment site for the
muscles of the tongue.
