Class Summary - Today we took a quiz on the skull, vertebrae and hyoid. Then we talked about the ribcage. The ribs protect the organs in the pectoral girdle. There are 7 true ribs and 5 false ribs (including 2 floating ribs #11 and 12). True ribs connect directly to the sternum and false ribs do not. The costal cartilage of the ribcage allows for movement to inhale and exhale. We also discussed the sternum which is 3 bones fused together. The manubrium, the body and the xiphoid process.
Homework - None
Objectives - Students will identify all of the bones in the axial skeleton.
