Ba-2 what does a slashing hand motin over the neck mean by a waterskiing participant

Explanation:

   It means that the person can no longer hold, close the hand, and depending on the location of the cut and depth, lose much blood quickly, because in the hand we have several arteries, including the radial artery. If you cut this artery, the person will die because in the blood will not stop.

  The radial artery is one of the terminal branches of the brachial artery (besides the ulnar artery), originating from the cubital fossa. In its path, it emits the radial recurrent artery and several branches to the hand. It also forms the deep palmar arch through an anastomosis with the deep branch of the ulnar artery.The resuls about this depth cut can be the, in the last case, the death. This person perhaps it would fall into the water, drown and could die not from cutting but from drowning. But if this cut is over the neck, is more danger, because we have the jugular and carotid arteries and can be fatal.
