Skull
The skull is separated into two categories of bones, the cranial and the facial bones. The bones are shown in the figure below.
The cranial bones are the ones that actually come into contact with the brain.
The cranial bones are:
- Frontal bone - the bone makes up your forehead
- Parietal bones - this pair of bones makes up the top and upper sides of your head
- Temporal bones - this pair is found at your 'temples', this is the area surrounding your ears
- Occipital bone - this bone makes up the back of your head and part of the base or lower portion of the head
- Sphenoid bone - this bone is found in the middle of the skull beneath the brain, it can be seen from several different perspectives
- Ethmoid bone - this bone if found deep to your nose and eyes, it is seen through the nasal openings and eye orbits
The facial bones are:
- Mandible bone - this is your lower jaw
- Maxilla bones - this pair of bones makes up your upper jaw
- Zygomatic bones - this pair of bones is commonly refered to as your 'cheek bones'
- Nasal bones - this pair makes up the upper bony portion of your nose
- Lacrimal bones - this pair of bones is found in the medial portion of your eye orbit
- Palatine bones - this pair of bones makes up the deeper portion of the hard palate (roof) of your mouth
- Vomer bone - this bone is seen from the inferior view and makes up the lower portion of your nasal cavity
