LAB 6. THE SKELETAL SYSTEM 1 | Page STATION 1. THE AXIAL SKELETON Textbook Readings: Ch 7 The Skeleton p.200-225 Objectives: 1) To be able to identify the bones which comprise the axial skeleton. 2) To understand the functions of the axial skeleton bones. 3) To identify radiologic findings related to bones of the axial skeleton. There are 80 bones making up the adult axial skeleton. The axial skeleton consists of the skull , vertebrae and thoracic cage . We cannot attempt to learn all the components of these structures in such a short amount of time. However, we will review the major bones of the axial skeleton at this station and help you to understand their major functions. The hyoid bone , a “U” shaped bone which lies anterior to the trachea and larynx, is the only bone which has no attachments or joints with another bone. This bone is included with the components of the axial skeleton. A. THE SKULL At your station you will find several models of the skull. As you examine the skull models you will note that the skull is composed of two sets of bones: 1) cranial bones and 2) facial bones . List TWO functions of the cranial bones. 1. _______________________________ 2. _______________________________ List FIVE functions of the facial bones 1. ______________________________ 2. ______________________________ 3. ______________________________ 4. ______________________________ 5. ______________________________
