Which of the following bones is classified as irregular in shape?

• patella

• frontal

• vertebra

• ulna

The region of a long bone between the end and the shaft is known as the ________.

• diaphysis

• epiphysis

• osseophysis

• metaphysis

Cells that secrete the organic components of the bone matrix are called

• osteocytes

• osteoprogenitor cells

• osteoblasts

• osteoclasts

Through the action of osteoclasts,

• new bone is formed

• an organic framework is formed

• bony matrix is dissolved

• fractured bones regenerate

The interconnecting tiny arches of bone tissue found in spongy bone are called

• osteons

• interstitial lamellae

• concentric lamellae

• trabeculae

The medullary cavity of bones contains

• osteons

• compact bone

• periosteum

• marrow

Endochondral ossification begins with the formation of a(n)

• calcified model

• osteoblasts model

• cartilage model

• membranous model

The following are major steps in the process of intramembranous ossification.

1. Clusters of osteoblasts form osteoid that becomes mineralized.

2. Osteoblasts differentiate within mesenchymal connective tissue.

3. Spicules of bone radiate out from the ossification centers.

4. Mesenchymal cells aggregate.

The correct order for these events is:

• 2, 1, 3, 4

• 4, 1, 2, 3

• 4,2,1,3

• 2, 3, 1, 4

Secondary ossification centers occur

• in the epiphyses

• at the periosteum

• in the diaphysis

• in the metaphyses
