    Study Notes

    Zygomatic Bones

    • Form the prominent structure of the cheeks and have a diamond shape.
    • Facilitate mastication by providing attachment points for the masseter muscle.
    • Articulate with sphenoid, maxilla, frontal, and temporal bones.

    Maxilla Bones

    • Positioned at the anterior portion of the face; comprises the upper jaw.
    • Supports teeth, lateral aspects of the nasal cavity, and portions of the eye socket.
    • Articulate with zygomatic, frontal, and palatine bones.

    Inferior Nasal Concha

    • Situated within the nasal cavity to enhance air contact with cavity walls.
    • Increases surface area for inspired air, aiding in filtration and warming.
    • Articulates with ethmoid, maxilla, lacrimal, and palatine bones.

    Lacrimal Bones

    • The smallest bones of the face, forming part of the orbit's medial wall.
    • Crucial for eye support and involved in tear drainage through the tear duct.
    • Articulate with frontal, ethmoid, maxilla, and inferior nasal concha.

    Maxillae (Paired)

    • Comprised of two joined maxillary bones forming the upper jaw.
    • Contributes to the greater upper facial skeleton and forms several facial structures.

    Mandible Bone

    • Constitutes the lower jaw, housing the lower teeth.
    • The largest skull bone, made up of the mandible body and ramus.
    • Articulates with the temporal bone to create the temporomandibular joint (TMJ).

    Vomer Bone

    • A single, thin bone positioned vertically in the nasal cavity.
    • Separates the left and right nasal cavities.
    • Articulates with maxilla, ethmoid, sphenoid, and palatine bones.

    Nasal Bones

    • Comprises two slender and elongated bones that form the nasal bridge.
    • Size varies among individuals and articulates with adjacent nasal, frontal, maxilla, and ethmoid bones.

    Total Number of Facial Bones

    • Total of 14 facial bones:
      • Vomer x 1
      • Conchae (Turbinate Bones) x 2
      • Nasal Bones x 2
      • Maxilla x 2
      • Mandible x 1
      • Palatine Bones x 2
      • Zygomatic Bones x 2
      • Lacrimal Bones x 2
