Facial and Cranial Bones

Just remember:

Con Man Max and Pal Ziggy Lack Nasty Voices while cranial bones are a PEST of 6.

Conchae (2)

Mandible (1)

Maxilla (2)

Palatine (2)

Zygomatic (2)

Lacrimal (2)

Nasal (2)

Vomer (1)

Parietal (2)

Ethmoid (1)

Sphenoid (1)

Temporal (2)

Occipital (1)

Frontal (1)

6 is the number of cranial bones.

Concha means shaped like a shell. If you look at the nasal conchae, they do look a little like conch shells. See Netter’s  slide 8.

Maxilla and mandible make up the jaw. Maxilla is on top, just remember its the max. Netter’s slide 6.

Palatine means related to the palate. The palatine bone is on the roof of the mouth, just before the soft palate in the back of your mouth. See Netter’s slide 8 and 10.

Zygomatic or Malar or Maxillary bones (not to be confused with maxilla). ‘zygo-‘ means to ‘unite.’ The zygomaticbonesjoin the viscerocranium (the face)to the neurocranium (the part of the skull that contains the brain). See Netter’s slides 4-6.

Lacrimal bones. Lacrimate means to produce tears. The lacrimal bones are right where you tear ducts are on the medial portion of your eye. They make up part of the medial orbit. See Netter’s slides 4-6.

Nasal bone. Nasal bone makes up the bridge of your nose. Pretty straightforward. See Netter’s slides 4-8.

Vomer bone. You’re going to have to go with me on this one. ‘Vomer’ means ‘plow’ in Latin. The vomer bone looks like a little plow when it is all by itself. It is the inferior division of the nasal cavity. (http://www.anatomyexpert.com/structure_detail/13/See Netter’s slide 4.

Parietal bones. ‘Paries’ means ‘wall’ in Latin. Parietal bones are the 2 lateral walls of the neurocraniumSee Netter’s slides 4-6.

Ethmoid bone. Ethmoid comes from the Greek ‘ethmos,’ meaning ‘sieve.’ It has many foramina on the superior edge in order to allow the olfactory nerves to penetrate into the nasal cavity. It is located inferomedially to the nasal and frontal bones. The superior and middle nasal conchae make up part of the ethmoid bone. See Netter’s slides 4-6.

Sphenoid bone. ‘Sphene’ means wedge in Greek. Personally I don’t think the sphenoid looks like a wedge, but maybe you see it. There is talk that sphenoid actually came from ‘spheco’ which means wasp. I do see a wasp, with the wings on each side of the skull. Whichever works for you is good with me. If you see the wasp, then it sits upright, right behind the orbits with it’s greater wings extending upwards to meet the parietal, temporal, and frontal bones. See Netter’s plates 4-11.

Temporal bones. I find the story of why these are called temporal interesting. So tempus means time in Latin. Hair on the temporal bone is usually the first to gray, showing the passage of time. See Netter’s Plates 4-11.

Occipital and Frontal bones, I think, are self explanatory. Occipital comes from the Latin ob- meaning opposite and caput meaning head, therefore opposite of head, I guess.
