1. The organ systems in the boy’s arm that the surgeon would’ve had to reattach are the circulatory, lymphatic, integumentary, muscular, skeletal and the nervous systems.
2. The specific structures that would’ve been reattached would be the humerus bone. Additionally, the muscles that would’ve been reattached are biceps brachii, brachialis, triceps, and the coracobrachialis. The nerves that would’ve been fixed would be the median, ulnar, radial, musculocutaneous, and the antibrachial cultaneous nerves. The brachial, superior and inferior collateral, profunda brachii arteries would have to be reattached, along with several smaller veins.
3. The system that was most likely not reattached would be the lymphatic. The lymphatic system is composed of small vessels that would be very difficult to reattach.
4. A clean shark bite is so important because it would tear less tissue, making it easier to reattach. Less damage would be done to the nerves and muscles in the arm, and after reattachment, use of the arm would be better.
5. It is shorted a little in order to clean up the bone, remove the damaged bone and even it out to make reattachment easier.
6. The movements associated in the arm, forearm, wrist, and fingers are flexion, extension, abduction, rotation, and adduction.
7. After reattachment, movement would be diminished because not all of the nerve fibers would necessarily be reattached.
8. Collateral circulation is the circulation of blood through modified vessels to certain areas. The areas of collateral circulation in the arm are the scapula, the upper head of the humerus, the elbow, wrist, and the hand.
9. The axillary artery, the brachial artery, and the subuvian artery are responsible for the collateral circulation in the upper extremity.
10. Jim could have trouble with clenching his hand into a fist and moving his individual fingers, because not all of the nerves and muscles were attached exactly as they were
