Pulsate: With blood flow and pressure, the artery walls will expand with each heart beat, then relax and deflate a bit, and the cycle continues with each heart beat. When you stand up, people can sometimes get a low blood pressure, due to the positional change, and the heart may try to compensate by increasing its heart rate, and therefore, this may be more noticeable in your neck.
