Study Notes

Maxillary Bones (Maxilla)

Form the majority of the skeleton of the face and the upper jaw
Contain the maxillary paranasal sinus
Articulate with the opposite maxilla and the frontal, nasal, vomer, and ethmoid bones; inferior nasal concha; palatine, lacrimal, and zygomatic bones; and the septal and nasal cartilages
2 maxilla bones (maxillae)
Parts:
- Body: major part of the bone, shaped like a pyramid, contains the maxillary paranasal sinus
- Frontal process: extends superiorly to articulate with the nasal, frontal, ethmoid, and lacrimal bones, forms the anterior boundary of the lacrimal fossa
- Zygomatic process: extends laterally to articulate with the maxillary process of the zygomatic bone
- Palatine process: extends medially to form the majority of the hard palate, articulates with the palatine process of the opposite side and the horizontal plate of the palatine bone, incisive foramen is located in the anterior portion
- Alveolar process: the part of the maxilla that supports all of the maxillary teeth, extends inferiorly from the maxilla, each maxilla contains 5 primary and 8 permanent teeth, alveolar bone is resorbed when a tooth is lost

Nasal Bone

Inferior portion forms the superior margin of the nasal aperture
Forms the bridge of the nose
Articulates with the nasal bone of the opposite side, the nasal portion of the frontal bone, the frontal process of the maxilla, and the perpendicular plate of the ethmoid
Inferior portion of the nasal bones attaches with the lateral nasal cartilages and septal cartilage
2 nasal bones

Lacrimal Bone

Small and rectangular in shape, thin and fragile
Forms a small portion of the medial wall of the orbit
Articulates with the frontal process of the maxilla, orbital plate of the ethmoid bone, the frontal bone, and the inferior nasal concha
The region that articulates with the frontal process of the maxilla forms the lacrimal fossa, the location of the lacrimal sac
The inferior part of the lacrimal forms a small portion of the lateral wall of the nasal cavity
2 lacrimal bones

Vomer

Shaped like a "plough"
Forms the posterior inferior part of the nasal septum
Articulates with the perpendicular plate of the ethmoid, maxilla, palatine, and sphenoid bones and septal cartilage
Posterior border does not articulate with any other bone
1 vomer bone

Palatine Bone

Forms part of the nasal cavity and the hard palate, L-shaped
2 palatine bones
Parts:
- Perpendicular plate: vertical rectangle, notch on the superior border articulates with the sphenoid bone, forming the sphenopalatine foramen, small orbital process helps form part of the orbit, forms part of the wall of the pterygopalatine fossa and the lateral wall of the nasal cavity
- Horizontal plate: forms the posterior portion of the hard palate, superior to the horizontal plate is the nasal cavity, on the medial part is the posterior nasal spine, greater palatine foramen is on this plate
- Pyramidal process: extends posteriorly and inferiorly from the junction of the perpendicular and horizontal plates, lesser palatine foramina are located here

Inferior Nasal Concha

Curved bone that forms part of the lateral wall of the nasal cavity
2 inferior nasal conchae
Lies within a curve in the lateral wall of the nasal cavity
Articulates with the maxilla and perpendicular plate of the palatine, lacrimal, and ethmoid bones

Mandible

Forms the lower jaw
Described as horse shoe shaped
All muscles of mastication attach to the mandible
1 mandible
Parts:
- Body: mental foramen is located on the body
