GENERAL CHARACTERISTICS
- Thin unpaired bone located in the midsagittal plane
- Constitutes the inferior portion of the nasal septum
- Functions to divide left and right nasal passages
- Essential for nasal cavity structure and function
ARTICULATIONS
Vomer Bone - Disarticulated View, Preview from the app. Download 3D OSTEOLOGY for full 3D control—multiple views, x-ray mode, and unlimited zoom.
- Connects with multiple cranial and facial bones:
- Sphenoid bone
- Paired maxillae
- Paired palatine bones
- Ethmoid bone
SUPERIOR BORDER
Alae of Vomer
- Bilateral wing-like extensions from the superior margin
- Project laterally from the superior margin
- Articulate with sphenoid bone:
- Via vaginal processes of medial pterygoid plates
- Articulate with palatine bones:
- Via sphenoidal processes
- Anchor the vomer securely within the skull
SURFACES
Vomerine Groove, Sourced from the app 3D OSTEOLOGY
Vomerine Groove
- Oblique indentation on the bone surface
- Provides passage for blood vessels
- Accommodates nerves supplying the nasal septum
POSTERIOR BORDER
Vomerine Crest of Choana
- Posterior margin feature of the vomer
- Contributes to formation of the choanae
- Choanae serve as openings between nasal cavity and nasopharynx
ANTERIOR ASPECT
Cuneiform Part
- Wedge-shaped anterior portion
- Articulates with perpendicular plate of ethmoid bone
- Connects with septal cartilage
- Completes the nasal septum
FUNCTIONAL SIGNIFICANCE
- Ensures proper separation of nasal passages
- Critical for efficient airflow
- Important for olfactory function
