حَبلِ الوريدNot Jugular vein but means Vocal Cord.
Quran e Majeed had informed mankind, 1400 years back, as follows:سَنُرِيهِمْ آيَاتِنَا فِي ٱلآفَاقِ وَفِيۤ أَنفُسِهِمْ حَتَّىٰ يَتَبَيَّنَ لَهُمْ أَنَّهُ ٱلْحَقُّ
"We will keep making it visible to the eyes of those who do not accept Quran, the signs/knowledge in the Universe and in their own bodies till it becomes evident for them that this Quran is a statement of proven fact" {Refer 41:53}
The Grand Quran has informed that Allah will keep revealing, the knowledge about the universe and human body, and it will become manifest to the people that the Quran is a statement of proven fact. Why would it become manifest that the Quran is a statement of proven fact when man sees/perceives new knowledge about universe and human body? If the things mentioned in a book written earlier in time and space are subsequently found a scientific fact only then it is evident to people that the Book is really a statement of proven facts and not conjectural and presumptive.
Allah has informed us:وَلَقَدْ خَلَقْنَا ٱلإِنسَانَ وَنَعْلَمُ مَا تُوَسْوِسُ بِهِ نَفْسُهُ وَنَحْنُ أَقْرَبُ إِلَيْهِ مِنْ حَبْلِ ٱلْوَرِيدِإِذْ يَتَلَقَّى ٱلْمُتَلَقِّيَانِ عَنِ ٱلْيَمِينِ وَعَنِ ٱلشِّمَالِ قَعِيدٌمَّا يَلْفِظُ مِن قَوْلٍ إِلاَّ لَدَيْهِ رَقِيبٌ عَتِيدٌ
"And indeed We have created the man. And We know with what thought {heart} inspires his self. And We are nearer to that thought than the cord that makes reach, when it is taken/received from right side and left side by the two Receivers, each sitting on one side. Man does not throw away any word from his statement except that there is always one near him alert to take that {for recording}" {Ref 50:16-18}.MORE
