The Cringe Muscle

You know that face you make when something is cringeworthy? The one where your mouth get's wide and the front of your neck all the way across your clavicles flattens out? Believe it or not, there is one muscle that is mostly responsible for that! It's called your platysma. It's a flat sheet that sits over the top of all of your other neck muscles, and acts as a muscle of facial expression.
