Understanding the 14 Bones of the Human Face: Key Functions and Features

This informative guide explores the 14 bones that structure the human face, highlighting their paired and unpaired classifications. The maxillae, zygomatic, nasal, inferior nasal conchae, lacrimal, palatine, vomer, and mandible all play crucial roles in both form and function. Discover how these bones contribute to our facial structure, support for muscles, and pathways for nerves and blood vessels. Learn about the significance of each bone, including the unique features of the mandible, the upper jaw, and the delicate design of the lacrimal bones.

  1. Face Time! 14 bones to know

  2. Lets start with the 14 bones of the face Paired • Maxillae • Zygomatic • Nasal • Inferior nasal conchae • Lacrimal • Palantine bone Not paired • Vomer (not paired) • Mandible (not paired)

  3. 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

  4. 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

  5. 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.

  6. Nasal Bones • 2 bones fused medially bridge of nose

  7. Lacrimal Bones • Delicate finger nail shaped bones contribute to the medial walls of each orbit

  8. Lacrimal bones • Help to form the lacrimalfossa houses lacrimal sac part of passagway that allows tears to drain

  9. Palatine Bones • L shaped bone

  10. Vomer Bone • Lies in the nasal cavity, forms part of the nasal septum

  11. Inferior Nasal Conchae • Thin curved bones found in the nasal cavity. • Form the lateral walls of the cavity
