Which muscle retracts the angle of the mouth when you laugh?
Which muscle retracts the angle of the mouth when you laugh?
Tap to reveal answer
We are looking for a muscle around the mouth, leaving us with the risorius, orbicularis oculi, and zygomaticus minor muscles. The orbicularis oculi protrudes the lips and the zygomaticus minor elevates the upper lip. This means that the correct answer is the risorius muscle.
