(bottom half is vomer)

Upper 2/3 of the lateral wall of nasal cavity (superior and middle nasal concha)
(Bottom is inferior nasal concha)

Holes serve as passageways for olfactory nerve

17
Q

Sphenoid bone

A

Wing between the frontal and temporal bone
Comprises the bony floor of the brain
4 Landmarks:
1. Lateral pterygoid
2. Medial pterygoid
3. Hamulus
4. Pterygomandibular ligament/raphe

18
Q

Lateral pterygoid

A

Paired vertical bony inferior projection that is most lateral

19
Q

Medial pterygoid

A

Paired vertical bony inferior projection that is most medial
Has the hamulus
Site of pterygomandibular ligament/raphe

20
Q

Hamulus

A

Hook-like projection of medial pterygoid

21
Q

Pterygomandibular ligament/raphe

A

Extends from hamulus on medial pterygoid to mandible
Boundary between the superior constrictor and buccinator
