Discuss Midterm Exam Questions

LE Unit Overview  Skeletal structures / joint surfaces  Ligamentous support  Musculature / vasculature  Nerves  Forces and injuries  Superficial fascia, veins, lymph

Objectives  Describe the gross anatomy for each system (circulatory, muscular, nervous, and skeletal) in the upper extremity.  Integrate the systems to discuss the upper extremity stability and mobility functions.  Analyze common injuries in the upper extremities.  For each muscle, describe how the attachment sites result in an action around a joint.  For each muscle, identify the innervation (peripheral nerve and nerve roots).
