on the elbow joint there is a tendon called the "golgi organ" it is used to effectively destroy an elbow joint, where is it, how hard should it be stricken, and how much force does it then take to bend the elbow the other way? also if there are any other quick shots that could incapacitate an opponent like blackouts or breaks? I also don't care about legal issues so don't bore me, tell me what i want to know
