Yolanda is asked to review a bone slide that her professor has set up under the microscope. She sees concentric layers surrounding a central cavity. Is this bone section taken from the diaphysis or the epiphyseal plate of the specimen?

If a person's spongy bone were all replaced by compact bone, how may that affect the function of their bones and skeleton?

Correctly order the following steps of bone growth in length, by placing a 1 by the first step, a 2 by the second step, and so on.

______Calcified cartilage is replaced with bone in the zone of ossification.                   

______Chondrocytes in the zone of proliferation divide by mitosis.                   

______Chondrocytes enter the zone of calcification and die as their matrix calcifies.                   

______Chondrocytes enlarge and cease dividing.
