Laboratory 10.  The Skeletal Muscular System and Muscles of the Upper Extermities

   

During this laboratory you will learn the major structures of skeletal muscle fiber, in addition to learning how to classify and name skeletal muscles.  You will then spend time studying the muscles of the chest, shoulder and upper limb.  By the end of this laboratory you should be able to describe and demonstrate the action of each muscle in addition to locating its' origin and insertion.

As always, your photographic atlas, textbook, and the websites listed below are excellent resources to help you study this material.  

Key Words: 

(You should be able to define or explain these terms.)
Tendon Aponerouses Origin
Insertion Parallel Fascicular Arrangement Convergent Fascicular Arrangement
Circular Fascicular Arrangement Pennate Fascicular Arrangement Prime Movers (Agonists)
Antagonists Synergists Fixators
