Look at your notes on the microscopic structures

of the bone & answer the following questions:

1. What are the circular structures present in the

compact bone & absent in spongy bone?

2. The layers of the osteon are the ______________.

3. In between each layer there are the ___________

Which are the spaces containing the osteocytes.

4. What are the 2 canals within the bone?

The canals contain: ______________ Is the bone above mature?

The little canals are the ______________. What is the other name for bone tissue?

Label the types of bone cells represented in this diagram.

For the test you should also be able to:

*Label the steps of endochondral ossification (look at your worksheet!)

*Compare and Contrast intramembranous and endochondral ossification.

*Recognize the characteristics and causes of the 5 skeletal disorders we discussed in class.

*Classify and Identify the types of fractures.

*Describe the steps in the repair of fractures.

*Differentiate between the axial and appendicular portions of the skeleton.

*Label the bones of the skeleton (including the skull bones and its parts).

*Compare the male vs. female skeletal structure.

*Identify the divisions of the vertebral column (cervical, thoracic, lumbar, sacrum, coccyx and how many vertebrae are in each) and the vertebrae components (spinous process, transverse process, intervertebral foramen, and body).

*Identify the different types of joints.

[pic]

1. The stem cells of bone that generate all bone cells by mitosis.

2. The bone cells that form bone by laying down the calcified matrix.

(In the lacunae of the bones matrix)

3. The mature bone cell that is within the bone structure responsible for daily cell activity

Compact Bone

Spongy Bone

(destroys matrix)

(osteoblast comes in behind to make new bone)
