Skull Skeletal System
The Skull consist of 22bones. The bones of the cranium protect the brain and provide muscle attachment points for muscles of the skull.
- Frontal Bone – this forms the forehead and the upper part of the eye sockets.
- Parietal bone – this forms the roof of the cranium. We recognize this as the anterior fontanelle.
- Occipital bone – this forms the back of the cranium.
- Temporal bone – this forms part of the sides of the cranium situated above the ears.
- Sphenoid bone – this forms the upper floor base of the cranium – a bridge between the facial bones and the cranium.
- Ethmoid bone – this forms part of the eye socket and the roof of the nasal cavity and art of the nasal spectrum
- Lachrymal bone – bones found medically within the orbital cavity (eye sockets)
- Turbinate bone – these located either side of the walls of the nasal cavity.
- Vomer bone – facial bone at the back of the nasal spectrum
- Palatine bone – bones that form the anterior portion of the roof of the mouth.
- Zygomatic arch – bones either side of the face forming the cheek bones.
- Maxilla – bones that form the upper part of the jaw and contain the upper teeth at the front of the face.
- Mandible – lower jawbone contains the lower teeth.
- Mastoid – situated on the lower edge of the occipital bone.
- Nasal – bones that extend forward from the base of the frontal bone.
