2. Zygomatic
3. Nasal
4. Inferior nasal conchae
5. Lacrimal
6. Palantine bone
Not paired
• Vomer (not paired)
• Mandible (not paired)
Mandible
• Lower jaw—u shaped
• Coronoid process insertion point for
temporalis muscles
• Mental foramina allow for the passage of
blood vessels and nerves that pass to the skin
and chin
Maxillary Bones
• Upper jaw
• All bones except the mandible articulate with
this bone
• Frontal processes extend superiorly to the
frontal bone lateral aspects of bridge of
nose
Zygomatic Bones
• Cheek bones
• Articulate with the zygomatic processes of the
temporal bones posteriorly and the zygomatic
process of the frontal bone superiorly and
with the zygomatic processes of the maxillae
anteriorly.
Nasal Bones
• 2 bones fused
medially bridge of
nose
Lacrimal Bones
• Delicate finger nail shaped bones
contribute to the medial walls of
each orbit
Lacrimal bones
• Help to form the
lacrimal fossa houses lacrimal sac part of
passagway that allows tears to drain
Palatine Bones
• L shaped bone
Vomer Bone
• Lies in the nasal cavity, forms part of the nasal
septum
Inferior Nasal Conchae
• Thin curved bones found in the nasal cavity.
• Form the lateral walls of the cavity
