301 Muscles

My doctor has taken me off of work until Thursday. That means I will not be teaching Muscles 301. Brenda will be covering for me on Monday in Ottawa and on Tuesday in Lima. You are in very good hands with Brenda - she was my muscles instructor, and if she can teach me, don't you worry about a thing.

You will be covering the muscles that move the humerus. While learning the material keep in mind the concepts of:
1. If a muscle crosses a joint, it will have action at that joint.
2. If a muscle crosses two joints, it will have action at both joints.
3. If a muscle does not cross a joint, it will not have action at that joint.

Also,
1. Get as much free info from the name as you can.
2. From the free info figure where the general location is. That will help you with figuring what joint is involved.
3. Figure the action of the muscle.(consider the line of pull, muscles never push)
a. What joint?
b. Where does it cross?
c. How does it cross?
4. Learn the origin and insertion.
5. Compare the muscle to the rest of the group, including its synergists and antagonists.

You'll be learning about the rotator cuff - a very important structure. You can remember the muscles of the cuff by remembering:
Supraspinatus
Infraspinatus
teres minor (note the small "t" for minor)
Subscapularis

I'll be thinking about you on Monday and Tuesday. Let me know if you need me, the cell phone is up and running.
