1. How many bones make up the adult axial skeleton?

   80 bones (skull 22, hyoid 1, auditory ossicles 6, vertebral column 26, sternum 1, ribs 24)

2. How many bones form the adult skull?

   22 (8 cranial + 14 facial)

3. Name the 8 cranial bones.

   Frontal, 2 parietal, 2 temporal, occipital, sphenoid, ethmoid

4. Name the 14 facial bones.

   2 maxillae, 2 zygomatic, 2 nasal, 2 lacrimal, 2 palatine, 2 inferior nasal conchae, vomer, mandible

5. Which bones meet at the coronal suture?

   Frontal and the two parietal bones

6. Which suture lies between the two parietal bones?

   Sagittal suture

7. Which suture separates the parietal bones from the occipital bone?

   Lambdoid suture

8. Which suture joins the temporal and parietal bones?

   Squamous suture

9. What is the pterion and why is it clinically important?

   H-shaped junction of frontal, parietal, temporal (squamous) and sphenoid (greater wing). It overlies the anterior branch of the middle meningeal artery; a fracture here can cause an epidural hematoma.
