- 8 cranial bones
- 14 facial bones - 28 cranial bones (Elephants Fathers Only Sleep Past Ten)1. Ethmoid bone
2. Frontal bone
3. Occipital
4. Sphenoid bone
5+6. Parietal bones X2
7+8. Temporal bones X2 - 31. Ethmoid BoneForms the inner core of the facial skeleton.
Located at the roof of the nose between the 2 orbits.
Separates the nasal cavity from the brain. - 42. Frontal BoneForms the forehead.
- 53. Occipital BoneForms the posterior brain case.
-> Back + lower part of skull
- 64. Sphenoid BoneHelps to form the base of the cranium, the sides of the skull and the floors and sides of the orbits (eye sockets).
-> Situated in the middle of the skull. - 75+6. Parietal BonesForm the middle portion of the brain case. The bones are joined together by the mid-line of the sagittal suture.
- 87+8. Temporal BonesPair of bones situated at the sides and base of the skull. Supports the temple of the face + encloses the ear.

7+8. Maxillae X2
9+10. Nasal Bones X2
11+12. Palatine Bones X2
13+14. Zygomatic Bones X2 - 111. MandibleLower jaw bone.
Begins as a paired bone but fuses at the mid-line at 1 year.
Largest, strongest + lowest bone in the face.
Holds lower teeth in place. - 122. VomerForms a large part of the nasal septum between the left and right cavities of the nose.
- 133+4. Inferior Nasal CochaeSmall, scroll-like bones placed on the lateral surface of the nasal cavity.
- 145+6. Lacrimal BonesSmall bones almost completely hidden in the intact skull.
Form part of the eye socket.
Smallest + most fragile bones of the face.
- 157+8. Maxillae BonesUpper jaw -> make up the hard palate, nose and upper dental ridge.
- 169+10. Nasal BonesMake up the superior surface or 'bridge' of the nose.
- 1711+12. Palatine BonesForm part of the hard palate + nasal cavity
- 1813+14. Zygomatic BonesMake up the prominent structure of the cheekbones and outer side of the eye sockets.
- 19—1. Mandible = purple

3+4. Inferior Nasal Cocha = light green
5+6. Lacrimal = light blue
7+8. Maxilla = yellow
9+10. Nasal = pink
