1.Identify at least five organ systems in this region of the arm that the surgeon would have marked for reattachment. a.Integumentary
b.Skeletal
c.Muscular
d.Nervous
e.Cardiovascular
2.Within each system, list the names of the specific structures that had to be reattached. De specific! Go to the chapter on each system and identify the structures that you would find in the injured region. a.Integumentary- The hypodermis, dermis and epidermis, which is the skin, would all have to be reattached. b.Skeletal- The long bone called the humerus.

c.Muscular- The Biceps brachii, triceps brachii, brachialis, triceps brachii(long head) and triceps brachii(lateral head) d.Cardiovascular- Blood vessels and arteries. The brachial and ulnar collateral arteries, the Axillary, brachial, basalic, Median cubital, radial blood vessels. 3.What organ system was most likely not reattached? Explain. The nervous system would not reattach because nerve cells do not go through mitosis so they won’t grow back and reattach to each other. 4. Why was a clean bite so important? By it being a clean bite it was easier to attach the arm back on. There weren’t a lot of tissues that was shredded. 5. Why was the bone shortened? The doctor put a plate in his arm to keep the two parts of his arm together. 6. Identify the movements associated with the arm, forearm, wrist, & fingers. The movements are rotation and circumduction, extension, flexion, hyperextension, supination and pronation. 7.Explain how the movements of the reattached arm might be altered after the reattachment. The nervous system reattachment grew back together well but it did not function the same way. 8.Identify specific types of activities that might cause Jim problems after recovery. I would say weight lifting, baseball, basketball, and typing 9.Why would full use of his arm be unlikely? The likely hood of all the different tissues regenerating and having there full function are nearly nonexistent. Scar...
