Question Answer
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.

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
