| How many bones are in the skull? | 22 bones - 8 cranial bones - 14 facial bones |
| 8 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 |
| 1. Ethmoid Bone | Forms 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. |
| 2. Frontal Bone | Forms the forehead. |
| 3. Occipital Bone | Forms the posterior brain case. -> Back + lower part of skull |
| 4. Sphenoid Bone | Helps 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. |
| 5+6. Parietal Bones | Form the middle portion of the brain case. The bones are joined together by the mid-line of the sagittal suture. |
| 7+8. Temporal Bones | Pair of bones situated at the sides and base of the skull. Supports the temple of the face + encloses the ear. |
| 1 2 3 4 5 6 | 1 = Frontal Bone 2. Parietal Bone 3. Sphenoid Bone 4. Temporal Bone 5. Occipital Bone 6. Ethmoid Bone |
| 14 facial bones (Many Vermin In London Make Nuns Pity Zebras) | 1. Mandible 2. Vomer 3+4. Inferior Nasal Cochae X2 5+6. Lacrimal Bones X2 7+8. Maxillae X2 9+10. Nasal Bones X2 11+12. Palatine Bones X2 13+14. Zygomatic Bones X2 |
| 1. Mandible | Lower 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. |
| 2. Vomer | Forms a large part of the nasal septum between the left and right cavities of the nose. |
| 3+4. Inferior Nasal Cochae | Small, scroll-like bones placed on the lateral surface of the nasal cavity. |
| 5+6. Lacrimal Bones | Small bones almost completely hidden in the intact skull. Form part of the eye socket. Smallest + most fragile bones of the face. |
| 7+8. Maxillae Bones | Upper jaw -> make up the hard palate, nose and upper dental ridge. |
| 9+10. Nasal Bones | Make up the superior surface or 'bridge' of the nose. |
| 11+12. Palatine Bones | Form part of the hard palate + nasal cavity |
| 13+14. Zygomatic Bones | Make up the prominent structure of the cheekbones and outer side of the eye sockets. |
| 1. Mandible = purple 2. Vomer = dark blue 3+4. Inferior Nasal Cocha = light green 5+6. Lacrimal = light blue 7+8. Maxilla = yellow 9+10. Nasal = pink 11+12. Palatine = red 13+14. Zygomatic = dark green |
