The following images will walk you through the different bones of the human skull viewed from various angles. Bones of interest are highlighted in green.
1) The frontal bone is found...well on the front of the skull. So far so good.
The frontal bone articulates with 12 bones- the parietal bones (2), sphenoid bone, lacrimal bone (2), ethmoid bone, zygomatic bone (2), nasal bone (2) and the maxilla (2).
2) The occipital bone is found on the back (or posterior side) of the skull.
The occiptial bone articulates with 6 bones- the temporal (2), atlas, parietal (2) and sphenoid. This can be remembered with the pneumonic: OX TAPS...OX (occipital) T(temporal)A(atlas)P(parietal)S(sphenoid).
3) The parietal bone is found on the top of the skull. There is a right and left parietal bone which are connected by the sagittal suture.
4) The zygomatic bone is also known as the cheek bone. There is a right and left zygomatic bone.
5) The temporal bone.
6) The ethmoid bone looks small if only viewing the exterior portion, but it is actually quite large if viewed in isolation or with other bones faded from view.
7) The sphenoid bone also looks small if viewing the exterior of the skull but actually occupies a large area of the interior of the skull.
8) The lacrimal bone is a small bone found next to the nasal bones. There is a right and left lacrimal bone.
9) The nasal bone is found on the anterior side of the skull forming the structure of the front of the nose. There is a right and left nasal bone.
10) The inferior nasal concha are found in pairs (left and right).
11) The palatine bone is found in pairs (left and right).
12) The maxilla is found in pairs (a left and right).
13) The mandible is also known as the jaw bone.
14) The vomer is a small bone located in the nasal region.
15) The hyoid bone is a U-shaped bone in the neck (not technically part of the skull). It does not articulate with any other bones.
16) The skull also contains 3 small ear bones that exist in pairs (6 total bones)- the malleus, incus and stapes.
