Exam 6: Bone Tissue

Put the following in correct order for endochondral ossification. 1) Mesenchymal cells of the embryo develop into cartilage-producing cells. 2) The periosteum (formerly perichondrium) begins to produce a thin layer of compact bone. 3) A hyaline cartilage model of the future bone is formed. 4) Cartilage in the midregion of the model becomes calcified. 5) Spongy bone tissue develops at the primary ossification center. 6) Secondary ossification centers produce spongy bone tissue of the epiphyses. 7) Medullary cavity is formed.

On the basis of shape, the femur is an example of a _____ bone.

An osteon (haversian system) is

The connective tissue found on the articular surface at the end of a bone is called endosteum.

Mechanical stress on bone is due to the contraction of skeletal muscles and due to _____.

The artery entering near the center of the diaphysis is the _____ artery.

Normal bone growth and replacement depend on the presence of

The areas between neighboring osteons contain

Which of the following best describes a meatus?

The epiphyseal plate is

Canaliculi allow nutrients to diffuse to mature bone cells located within lacunae of the osteon. Which of the following are those mature bone cells?

In matrix formation, calcification precedes the secretion of collagen by osteoblasts.

The process of _____ ossification produces flat bones of the skull and the lower jawbone.

Activity of which of these cells is responsible for the remodeling of the bony callus as the final step in fracture repair?

Bone matrix contains crystallized mineral salts called hydroxyapatite.
