Shoulder clavicle?

i have see in movies and contained by tv that when someone presses the clavicle of other person the human being faints or sleeps how is this possible?Shoulder clavicle?
It may be the clavicle on show, but,
In real go, it is the carotid artery that is self compressed.
There is one on each side of the nouns and it is one of the major blood supplies to the brain.
Unless you own strong hands and thumb, you may know how to stop the flow of blood using just the thumb, however, most successful is to "pinch" it as tricky as you can-this stops the blood supply to the brain, thus the 'faint"
Its called a Vulcan Neck pinch and is made up by Gene Roddenberry.
There are principal arteries and veins within that area, if you did a "Judo Chop" sort of management you COULD stun a person with alacrity, but its not going to get you far.
the clavicle is certainly the BONE, your collar bine, but inbetween the collar bone an dthe muscle in your shoulder, put two fingers out and stab someone near your fingers rith next to your collar in tha nouns and you can make them go beyond out.
