The buccinator is a muscle of the mouth, involved in actions such as blowing and chewing. The corrugator supercilii is found above the eye and is responsible for frowning. The mentalis affects the chin, contributing to expressions like pouting, thus involving the mouth. The nasalis is involved with the nose, affecting nostril width and flare. The platysma is a broad muscle extending from the chest to the jaw, affecting the neck and lower face. The procerus is located between the eyebrows, affecting the nose area by drawing down the inner eyebrows, not the scalp. The risorius is a muscle of the mouth, involved in stretching the lips sideways.
