Welcome to the electronichuman anatomy and physiology frontier classroom of the 21st century. This test will concern itself directly with the human cranium. The skull has 28 irregularly shaped bones to form the structure. It consists of two major divisions: the cranium, or brain case, and the face. You will have unlimited number of attempts to help in learning and test-taking skills. Each attempt will result in a new set of questions and rearranged answers! I wish good luck and high grades on the human skull test.
