What area is primarily affected by the temporal nerve?

The temporal nerve primarily affects the muscle movements around the eyebrow. This nerve is responsible for supplying the frontalis and corrugator muscles, which are situated in the forehead and are involved in raising the eyebrows and making facial expressions. Its influence on the movement of the eyebrow can impact overall facial expression significantly. The choices identifying other areas, such as the cheek, jaw, and forehead, are influenced by other branches of the facial nerve or additional nerves but do not specifically reflect the primary association that the temporal nerve has with the eyebrow region. Understanding the role of the temporal nerve in facial anatomy is crucial for estheticians, particularly in contexts related to cosmetic procedures and facial treatments.
