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
