Study guide for skull bones

Below is a list of the bold-faced terms from the Conjoint 401 lab manual. They have been rearranged according to what can be seen in different views of the skull. The links take you to a skull tutorial developed by J. Crimando at Gateway Community College in Phoenix Arizona. The tutorial has four basic views of the skull, and by clicking on a region with your mouse, you can get the name for a bone or structure. You can learn many of the bones and landmarks from the tutorial, but you can also print out this list and use it when you are studying an actual skull in the lab. Note that the superior view is referred to as the interior view in the tutorial.


Superior view

(top of cranium removed; looking down from above)

Cranial Bones:

ethmoid bone
    cribriform plate with olfactory foramina
    crista galli

    superior orbital fissure (can see from posterior; can't see in tutorial)
    lesser wing
    greater wing
temporal bone
    jugular foramen
    internal auditory canal (can see from medial; can't see in tutorial)
    carotid canal
occipital bone
    jugular foramen
    foramen magnum
