Answer 1

Answer:

There is one last component of the axial skeleton we did not cover last lab: the thoracic cage, also called the rib cage. The thoracic cage surrounds and protects the heart and lungs in the thoracic cavity. It consists of the ribs, the sternum, and the thoracic vertebrae, to which the ribs articulate.

We examined the thoracic vertebrae last lab, so here we will only examine the ribs and sternum.
