All facial bones
R and L nasal R and L lacrimal R and L maxillary R and L zygomatic R and L palatine R and L inferior nasal conchae Vomer Mandible
Nasal bone form
superior bony wall of nasal cavity
Commonly called “bridge of nose”
Nasal bone articulate with
each other
Superior to nasal bone
frontal bone
Posterosuperior to nasal bone
perp plate of ethmoid
Lateral to nasal bone
maxillae
Vomer is a - in -
thin bone in floor of nasal cavity
Vomer forms
inf nasal septum
Superior border of vomer articulates w/
body of sphenoid
Superior part of ant border of vomer articulates w/
perp plate of ethmoid
posterior border is
free
Inferior Nasal conchae extends
diagonally & inf from lateral nasal cavity
- has a scroll like appearance
inf nasal conche
Upper two nasal conchae are processes of
ethmoid bone
two l shaped bones composed of vertical and horizontal plates
palatine bones
Horizontal plate articulate w/
maxillae
Zygomatic bones articulates superior w/
frontal bone
Zygomatic bones articulates laterally w/
zygomatic process of temp bone
Zygomatic bones articulates Anterior w/
maxilla
Zygomatic bones articulates posterior w/
sphenoid
Zygomatic bones form
prominence of cheeks
Temporal process extends posteriorly to join - of temp bone
zygomatic process
Zygomatic arch is formed by
union of temp process of zygoma & zygomatic process
inferior borders of spongy bone that support roots of teeth
Alveolar process
forward, pointed process at their midline junction
Anterior nasal spine
Maxillary bones form
three fourths of roof of mouth
Infraorbital foramen
located under each orbit for passage of infraorbital nerve and artery
Largest immoveable bones of face
Maxillary bones
Maxillary bones articulate with
frontal and ethmoid bones
- no w/ mabdible
maxillary bones form
lateral walls, floor of nasal cavity, floor of orbit
two smallest bones in skull
lacrimal bones
Lacrimal bones located in - between - and -
anterior part of medial wall of orbits between labyrinth of ethmoid and maxilla
Each lacrimal bone contains a
lacrimal foramen through which the tear duct passes
Lacrimal bones articulate w/
Frontal
Ethmoid
Maxilla
Inferior nasal concha
