NOTE THAT THERE ARE 3 THREADS FOR THIS WEEK!
We are continuing with THREADED Discussions this week.
There are 3 topics to choose from this week, there should only be 3 total Discussion threads.
Only ONE (1) very long thread for each:
Shoulder Girdle
Shoulder
Elbow
What then follows the beginning of each thread is a great discussion.
If there is a thread that is already started, please do not start another one on the same topic.
Thank you for your attention to this.
================================
THREAD 1: SHOULDER GIRDLE

Discuss what happens in the shoulder girdle on your right.
What muscles activate?

In each chapter on the upper extremity, you will be analyzing the activity of placing a plate in a cabinet, then removing the plate and placing it on the counter. Perform those tasks and then analyze how the subject these pictures performed those tasks.
Describe the position of the scapula in each picture
How does is change while moving between pictures?
Discussion Guidelines
THREAD 2: SHOULDER JOINT
Shoulder joint musculature
1. Stand in the anatomical position and hold a backpack in one hand with the elbow extended.
What force is acting on the shoulder joint?
What muscles are acting at the shoulder joint to counteract the force produced by the backpack?
What muscles acting at the shoulder girdle to counteract the force produced by the backpack?
What if one of these muscles fails? What is the result?

Describe the position
Describe which muscle groups are acting between picture 1 and 2, or 2 and 3
Describe the type of muscle contraction being used and why between picture 1 and 2, or 2 and 3

Consider the elbow flexor muscles: In the sitting position, place your elbow at 90 degrees of elbow flexion with the shoulder in anatomical position. Vary the position of the forearm from supinated, pronated, and midposition. In each position, try to hold the elbow flexed as you try to extend the elbow. with your other arm.
Did the position of the forearm affect the strength of the elbow flexors? Discuss.
