corporisfabrica:

The vasculature and underlying musculature of the neck and surrounding regions. 
Ascending the side of the neck is the common carotid artery. When you take your pulse at the side of your neck (try placing a finger just beneath the rear corner of the jaw), it is the pressure wave caused by ventricular systole of the heart that is felt in this vessel.
