• frontal bone
• nasal bones
• lacrimal bones
• maxilla
• palatine bones
• zygomatic (malar) bone
• ethmoid bone
• vomer
• inferior nasal conchae
• mandible
• hyoid bone

• forehead,
• forms superior portion of orbit

two small bones forming the bridge of the nose

• lateral to the nasal bones
• contains groove for nasolacrimal duct through which tears flow from the eye to the nasal cavity

• upper jaw
• palatine processes: horizontal projections forming anterior 2/3 of the hard palate (roof of mouth)

horizontal projections forming anterior 2/3 of the hard palate (*roof of mouth)

unite at midline to form posterior 1/3 of hard palate

• cheek bone
• temporal process: long, slender process of temporal bone that fuses with the maxilla to form the zygomatic arch

long, slender process of temporal bone that fuses with the maxilla to form the zygomatic arch

• small portion of the ethmoid bone enters the nasal cavity
• perpendicular plate
• superior and medial nasal conchae (turbinate bones)

forms the upper portion of the nasal septum

scroll-shaped plates of bone extending laterally from the perpendicular plate

• forms the inferior portion of the nasal septum
• articulates with the prependicular plate superiorly and hard palate inferiorly

scroll shaped plates of bone protruding from lateral, inferior walls of the nasal cavity

• lower jaw.
• condyles articulate with the mandibular fossae to form the temporomandibular joint
• mental foramina

small holes for the passageway of nerves and blood vessels

• horseshoe-shaped bone inferior to the mandible
• does not articulate with other bones
• held in place by various ligaments
• serves as attachment site for tongue and mouth muscles
