The occipitofrontalis is a muscle located in the scalp, consisting of two main parts: the frontal belly and the occipital belly. The frontal belly is responsible for raising the eyebrows and wrinkling the forehead, while the occipital belly helps to pull the scalp backward. Together, these muscles play a crucial role in facial expressions. This muscle is innervated by the facial nerve, which controls the movements of the face. The occipitofrontalis is important for non-verbal communication, allowing individuals to express emotions such as surprise or curiosity through facial movements.
