Question Set 1

1. Describe the functions of the skeletal system2. What is spongy bone? Where is it found?3. Describe the steps of endochondral

ossification4. What is a synarthrotic joint? What is an

example of one?5. What does hematopoiesis mean?

Case Study 1

Agnes is an elderly woman with osteoporosis. She recently sustained a severe bone fracture for no apparent reason (she did not fall or otherwise injure herself). The fracture was not treated for some time, and as a result, Agnes developed osteomyelitis. Based on what you know about osteoporosis, how do you explain her mysterious fracture? How can a fracture progress to osteomyelitis?

Question Set 2

1. Define the subtypes of diarthroses and give an example of each.

2. Explain how the articulating bones in a synovial joint are held together.

3. What is a fracture? Distinguish several principal kinds.

4. What is the difference between an osteoblast and an osteoclast?

Case Study 2

Archaeologists discover skeletal remains of humanlike animals in Ethiopia. Examination of the bones suggests that the remains represent four types of individuals. Two of the skeletons have bone densities that are 30% less than the other two. They also have broader front pelvic bones. Within the two groups defined by bone mass, smaller skeletons have bones with evidence of epiphyseal plates, but larger bones have only a thin line where the epiphyseal plates should be. Give the age group and gender of the individuals in this find.

Question Set 3

1. Sketch a long bone, lable its epiphyses, diaphsis, medullary cavity, periosteum, and articular cartilage.

2. Explain the function of the epiphyseal plate.3. What is an osteon? How does the central

canal relate to the osteon?
