This is the inner layer of the membrane which surrounds the outside surface of bone (shown at the arrow in Figure 9.) The membrane is called the __________ and the inner layer contains_________.

Bone growth and remodeling depends on adequate intake of:

Correctly order the following key steps in the process of endochondral ossification.1. Chondrocytes die.2. Osteoblasts build the bone collar on the external surface of the bone.3. Perichondrium is invaded by blood vessels.4. In the primary ossification center, osteoblasts replace calcified cartilage with early spongy bone.5. Chondroblasts differentiate into osteogenic cells then into osteoblasts.

Which of the following structures in a bone persists for life?

Figure 2 is an adult long bone. Choose the letter of the correct location of which the Functional unit is the Osteon and is located on the diaphysis.

Osteoblasts are to bone deposition as:

The layers of bone tissue immediately deep to the periosteum are:

Figure 5 shows the formation of a “bone collar” (at the black arrows) during the ossification process. It is composed of _____ bone and is produced by____.

Place the following steps of bone repair in the correct sequence. 1.The bone callus is remodeled and primary bone is replaced with secondary bone. 2.A hematoma fills the gap between bone fragments. 3.Osteoblasts build a new bone callus. 4.Fibroblasts and chondroblasts infiltrate the hematoma and a soft callus forms.

Figure 2 is an adult long bone. Choose the letter of the correct structure that lines the medullary cavity.
