These review questions are for the Skeletal system lecture topic. The questions were adapted from several sources, including 1700+ Review Questions for Anatomy and Physiology II (3rd edition) by R. Michael Anson, Ph.D. Questions marked with an asterisk (*) are questions from the laboratory, not the lecture, portion of the class.
You are required to know and understand all the material on the skeletal system that is covered in the lecture and the laboratory. To aid in your review of skeletal system anatomy, a list of bones and bone features is given below. For each of the bones or bone features listed below, be able to (a) find its location on a skeleton, (b) state if it is part of the axial or appendicular
skeleton, (c) state what bones it articulates with, and (d) describe its function.
