Question Set 1
1. Describe the functions of the skeletal system
2. What is spongy bone? Where is it found?
3. Describe the steps of endochondral
ossification
4. 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?
