Is there a pulse in your index finger?

There is a pulse everywhere in you body. Your pulse is the number of times your heart beats in a minute and so if there is no "pulse" in any area of the body it is not receiving blood from the heart and will die pretty quick. There is however not usually a strong enough pulse in the index finger for it to be detectable by human senses (this is why we use the index finger and not the thumb for taking a pulse). There are obvioulsy machines that can sense it and these are used in some forms of polygraph and I believe by psychologists testing levels of stress.
