Objective: Describe the movements of bones in the body.
Write in your notebook the types of joint movements and definitions or examples. (p. 157-159 in book)
Answer these questions:
1.
Sketch a typical long bone, and label its
epiphyses, diaphysis, medullary cavity, periosteum, and articular cartilage.
2.
Explain the function of an epiphyseal plate.
3.
Explain how upper limb movements function as
levers.
4.
What bones enclose the cranial cavity? For each
bone, explain where it is located and if there are any distinguishing characteristics
or features.
5.
Describe the differences among cervical,
thoracic, and lumbar vertebrae.
6. *Critical Thinking: 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 those of the other two
skeletons. The skeletons with the lower bone mass also have broader front
pelvic bones. Within each of the two groups defined by bone mass, a smaller
skeleton had bones with evidence of epiphyseal plates, but the other contained
larger bones with only a thin line where the epiphyseal plates should be. Give
the age group and gender of the individuals in this find, and explain how you
decided this.
