Bones and Features of the Skull
See Fundamentals of Anatomy and Physiology , Martini, 9th Ed, pp. 200-216 and The Anatomy Coloring Book, Kapit and Elson 3rd, pp. 24-26.
Illustrate two views of the skull:
- The floor of the cranium. (Martini’s 9th, p. 203). (Note the eight bones which form the floor: frontal, ethmoid, sphenoid, two temporals, two parietals and the occipital)
- The right-front side (3/4 view)
Label all bones with their listed features. Use the illustrations in Martini to aid in locating the bones and their features.
Here is an index page to many skull bone pictures not included on this page.
Here are overall views of the skull:

Here is a (spooky) view up the nose showing the perpendicular plate, the cribriform plate and the middle nasal concha.
