The ‘Pucker Muscle’ and the ‘Smile Muscle’

The ‘pucker muscle’ that controls lip movement to shape sounds is the ‘orbicularis oris’ muscle.

The’ zygomaticus major’ runs from your cheekbone to the corners of your mouth to help create smiles and other facial expressions, as well as sounds such as ‘eee’. (Fun fact: This muscle can contract with a force of 200 g.[1])
