Shark Attack

5 organ systems that were involved in this surgery was the integumentary system, the muscular system, the nervous system, skeletal and the circulatory systems. Integumentary was involved because they had to assure that there was a clean cut on the surface and that they’d be able attach cleanly. Muscular was involved because they had to reconnect all of the muscles in the boys upper arm to the lower portion. Nervous system was involved because in order the arm to be “alive” the nerves had to be re-connected and working. Skeletal because the orthopedic doctor had to trim down the bone and insert a plate that would allow for the reconnection and ultimately shortening the arm. Lastly the Circulatory system is involved because they doctors had to reconnect the blood vessels to allow blood flow back into the arm.

The brachial and Axillary arteries, the humerus bone, and the bicep and tricep muscles (Arms).

The nervous system was most likely the one that wasn’t reattached due to the fact that nerves are hard to fix and the doctor told the parents that he would never use his arm like he use to.

If there is a clean bite then that means that there isn’t a terrible amount of tear in the muscle/tissue.

As the doctor said, they had to trim both sides of the bone in order to make it fit back together with the plate intact.

The movements of the arm and fingers include rotation, extension, flexion, hyperextension and abduction (Arms).

As stated in question 3, the nervous system will never be like it use to therefore he will not gain back full use of his arm or fingers, but his muscles will work pretty close to normal which will aid in him gaining back some range of motion.

Collateral Circulation is when minor blood vessels become enlarged and join with adjacent vessels when a major artery is impaired or obstructed (Collateral Circulation). Arteries that would’ve been effected are the Brachial and axillary.

The brachial would connect to the Ulnar artery and the Radial...
