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.
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
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
