2. Facial bones Nasal Lacrimal Palatine Inf nasal conchae Maxillae Vomer
Zygomatic
Mandible

3. Nasal bones. Lacrimal bones
Small, fattened, rectangular shape
Major portion is made up of cartilage
Smallest
Post-lateral
Medial wall of each orbit
Contain lacrimal fossa

5. Palatine inf nasal conchae
Post portion of hard pallate
Floor, lateral wall of nasal cavity
Inf lateral wall of nasal cavity

6. Vomer. Maxillae Triangular Superior- ethmoid, sphenoid
Inf maxillae and palatine
Divide nasal cavity into right left
Articulate wiyh every bone, bt mandible
Orbit floor
Lateral wall, floor of nasal cavity
Most of the hard palate
Maxillary sinus

8. Zygomatic. Mandible Cheek bones Lateral wall and floor of each orbit
Articulate with frontal, sphenoid, temporal, maxilla
Temporal process
Largest strongest facial bone
Only movable skull bone

10. Nasal septum
Nasal cavity devided into right left vertical portItions called nasal septum
Vomer, septal cartilage and Plate of ethmoid bone

11. Orbits 7 bones= 3 cranial frontal, sphenoid, ethmoid
4 facial palatine, zygomatic, lacrimal, maxilla
Frontal sphenoid= roof
Zygomatic sphenoid = lateral wall
Maxilla zygomatic palatine= floor
Maxilla lacrimal ethmoid sphenoid= medial wall

12. Foramina

14. Sutures Immovable joints, only in skull Children...often movable
1. Coronal suture: frontal parietal
2. Sigittal suture: parietal bones
3. Lambdoid suture: parietal occipital
4. Squamous suture: parietal temporal

16. Paranasal sinuses
Cavities in certain cranial and facial bones near the nasal cavity
Lined with mucus membranes
Frontal sphenoid ethmoid maxilla
Resonating chamber

17. Fontanels
Newly formed embryo consists of cartilage or mesenchyme- arranged in sheetlike layers that resembles membranes shaped lime the bones they will become. Anterior fontanel months Post...2 months Anterio lateral...3 months Posterio lateral...12 months

18. Hyoid bone = u shaped Suspended from styloid process of temporal bones
Ant neck between mandible larynx
Body, lesser horns, greater horns
Often fractured duting strangulation
