1. match the bone names in column b with the descriptions in column a. (some responses may be used more than once.)

column a

1. bone forming anterior cranium
2. cheekbone
3. form the superior and lateral cranium
4. bony skeleton of nose
5. posterior hard palate
6. bone pair united by the sagittal suture
7. site of jugular foramen and carotid canal
8. contains a \saddle\ that houses the pituitary gland
9. allows tears to drain
10. forms most of hard palate
11. superior and middle nasal conchae are part of this bone
12. site of external acoustic meatus
13. has greater and lesser wings
14. its \holey\ plate allows olfactory fibers to pass
15. facial bone that contains a paranasal sinus
16. three cranial bones containing paranasal sinuses
17. its oval-shaped protrusions articulate with the atlas
18. forms the chin
19. not really a skull bone
20. spinal cord passes through a large foramen in this bone
21. inferior part of nasal septum
22. contain sockets bearing teeth

column b
ethmoid
frontal
hyoid
lacrimal
mandible
maxilla
nasal
occipital
palatine
parietal
sphenoid
temporal
vomer
zygomatic

Explanation:

Identify anterior cranium and cheekbone

Using the Skeletal Anatomy knowledge point, we match the first two descriptions. The bone forming the anterior cranium is the frontal bone. The cheekbone is the zygomatic bone.

Identify cranial vault and nasal structures

Using the Skeletal Anatomy knowledge point, the parietal bones form the superior and lateral cranium. The nasal bones form the bony bridge/skeleton of the nose. The palatine bones form the posterior portion of the hard palate. The sagittal suture unites the pair of parietal bones.

Identify cranial base landmarks and sinuses

Using the Skeletal Anatomy knowledge point, the temporal bone contains the jugular foramen, carotid canal, and external acoustic meatus. The sphenoid bone contains the sella turcica ("saddle" for the pituitary gland) and has greater and lesser wings. The lacrimal bone contains the lacrimal fossa allowing tears to drain. The maxilla forms most of the hard palate. The ethmoid bone contains the superior and middle nasal conchae, as well as the cribriform ("holey") plate for olfactory fibers.

Identify sinuses, articulations, and lower jaw

Using the Skeletal Anatomy knowledge point, the facial bones containing paranasal sinuses are the maxillae. The three cranial bones containing paranasal sinuses are the frontal, ethmoid, and sphenoid bones. The occipital bone has oval-shaped condyles that articulate with the atlas, and contains the foramen magnum for the spinal cord. The mandible forms the chin. The hyoid bone is suspended in the neck and not considered a skull bone.

Identify nasal septum and tooth sockets

Using the Skeletal Anatomy knowledge point, the vomer forms the inferior part of the nasal septum. The mandible and maxilla contain alveolar processes (sockets) bearing teeth.
