	Check out the BBC website. Can you move these muscles into their proper places?

LAB PRACTICAL "PRACTICE"

Muscular Tutorials

Click on the web address above and work through the various muscle tutorials. You may have to substitute some of the names we used in class for the ones on the diagram. Be sure to click on the muscle parts that you wish to identify.

STUDY TIPS

Learn the muscles in respect to the bones. Many have the same names or words that are similar to the bones.
Study your notes early. Don't wait until the last minute to get the terms straight in your head. It will only make learning the muscle names more difficult.
As in any unit, be sure to read the chapter, go over the outline and objectives, and check your knowledge by doing the quiz at the end.
Learn the diagrams at home and then compare them to the models at school. Don't try to learn all of the muscles in the ONE class period.

TEST QUESTIONS	WHAT TO STUDY
1-38 Matching muscular terminology	Notes and muscular lab
40-60 Muscle function	Muscle Lab
61-70 Body Movements	Review your body movement lab from skeletal system
20 pts. Constructed Response	Prefixes, Suffixes and Root words; how a muscle contracts; thinking skills

TEST REFLECTION

How did you do on this test in comparison to the skeletal test?
Why do you think it was easier to study the muscles than the bones?
What study skills have you begun to develop that you did not have before?
What study skills do you still have to develop?
