The nervous system was most likely no reattached, it would have been nearly impossible to reattach all the nerves in the arm and more than likely some would have died on the way to the hospital. This is why jim will probably never regain complete use of his arm again. 4. If the shark had ripped and shredded the muscles, veins or arteries it would have made it much more difficult to reattach the muscular and cardiovascular systems. A clean bite created clean lines and thus the surgeon could reattach more easily. 5. The joint have to be completely reconfigured, the arm would have to be cut to make it perfectly flat and smooth surface to reattach, this would cause a slight shortening of the bone. 6. Flexion: bending the elbow, clenching hand into fist. Extension: pull forearm back down after flexing, extending fingers. Abduction: spreading fingers apart, deltoid. Adduction: dropping the arms to the sides, closing fingers. 7. Raising the arm would be more difficult because deltoid motion will probably be extremely limited seeing as how that is the main muscle affected by the arm being bitten off. The range of motion in flexion and extension will probably also be decreased simply because of muscle cognition. 8. Collateral circulation: circulation of blood through a network of minor vessels that become enlarged and jointed with adjacent vessels when a major vein or artery is impaired. The brachial vein, cephalic vein, and basilica vein would be areas of collateral circulation that could have been affected by a shark bite. 9. The inferior ulnar collateral artery and the posterior ulnar recurrent artery provide the...
