Yes, I agree about the "rib."
In the light of present medical knowledge, the choice of a rib seems most appropriate. A rib that has been removed will grow again, replacing itself, as long as the periosteum (the membrane of connective tissue that covers the bone) is allowed to remain. Whether Jehovah God followed this procedure or not the record does not state; however, as man’s Creator, God was certainly aware of this unusual quality of the rib bones.
