Q&A: Is there a martial art technique/style that focuses on hitting the nerve spot of a person?

Question by Justme: Is there a martial art technique/style that focuses on hitting the nerve spot of a person?
I was watching this movie and it’s about a guy knowing some sort of martial art technique and he strikes his opponent at nerve centers making the opponent’s arm numb. I was wondering if this is based on something real. Is there actually a martial art style/technique that attacks blood flow, nerves system and internal muscle/organ?
