The 22 bones of the skull are organized into the 8 cranial bones and 14 facial bones. The skull serves multiple critical functions, such as cradling the delicate brain tissue and housing the major sensory organs. The foramina (holes) in the skull serve as passageways for nerves and blood vessels. Determine which of the following are a cranial or facial bone or a structure/foramina of one of these types. Carotid canal Nasal bone Styloid process Hypophyseal fossa Frontal bone Jugular foramen Mandible Palatine bone Cranial Facial

Step 1
There are 8 cranial bones. - **Facial Bones**: These are the bones that form the structure of the face. There are 14 facial bones. - **Structures/Foramina**: These are openings or processes (projections) in the bones that allow for the passage of nerves and blood Show more…

The Skull. First, match the bone names in column B with the descriptions in column A (the items in column B may be used more than once). Then, circle the bones in column B that are cranial bones. Column A 1. forms the anterior cranium 2. cheekbone 3. bridge of nose 4. posterior bones of the hard palate 5. much of the lateral and superior cranium 6. single, irregular, bat-shaped bone forming part of the cranial base 7. tiny bones bearing tear ducts 8. anterior part of hard palate 9. superior and middle nasal conchae form from its projections 10. site of mastoid process 11. has condyles that articulate with the atlas 12. small U-shaped bone in neck, where many tongue muscles attach 13. organ of hearing found here 14. two bones that form the nasal septum 15. forms the most inferior turbinate Column B a. ethmoid b. frontal c. hyoid d. inferior nasal conchae e. lacrimal f. mandible g. maxilla h. nasal i. occipital j. palatine k. parietal l. sphenoid m. temporal n. vomer o. zygomatic
The skull consists of two major regions. Describe these in this Checkpoint. Located in one pair of the cranial bones (the temporals are the tiny bones of the middle ear. Each middle ear contains (23?6?8? bones. The remaining bones of the skull are comprised of bones that provide a structural framework for the face. The total number of bones in the cranium, middle ears, and face is bones. Answer these questions on the cranium. a. What is the primary function of the cranium? List several other functions of the cranium.
