![]() However, the sphenoid is one large bone spans the cranium! That’s how you can remember this cranial bone: the sphenoid is the specter that spans the cranium! Don’t be fooled by the lateral skull view, because it appears as though the sphenoid is another pair of bones, just like the temporal and parietal bones. ![]() Many people think that it looks like a butterfly or bat, but it also looks like a specter (ghost). ![]() Sphenoid bone (1) – This butterfly-shaped bone articulates with all of the cranial bones and spans the entire width of the cranium, which you can see when you look at an inferior view of the skull.(Aren’t those anatomists so clever!) Forehead and frontal both start with an “F,” so this is probably the easiest cranial bone to remember. Guess what it’s called? It’s called the frontal bone. It makes up the FRONT of your cranium and also covers the frontal lobe of your brain. Frontal bone (1) – Look at your forehead.All the rest of the cranial bones are single and ready to mingle: We already have four of the eight cranial bones, so we’re halfway there. Guess what those paired bones are called? They’re called temporal bones! They are located just inferior (lower) to the parietal bones. Temporal bones (2) – If you get a headache from studying anatomy, you might want to massage the sides of your temples to relieve the pressure.As I mentioned in my video on body cavities and membranes, the word parietal means wall, and these bones make up the walls on the side of the cranium. The word parietal sounds similar to “pair,” so that can help you remember that there are two of them. Parietal bones (2) – The first pair of bones in the cranium are the parietal bones.I’ll cover the eight cranial bones first, starting with the two pairs of bones. The facial bones are the complete opposite: you have two single bones, and the rest are pairs! Here’s a cool thing to remember about the skull bones: in the cranium, two bones come in pairs, but all the others are single bones. The 22 skull bones make up part of the axial skeleton, and they can be divided into two main sections: the 8 cranial bones, and the 14 facial bones.
