superciliaris

Superciliaris refers to a muscular structure located in the brow region of the face. Specifically, it is often associated with the eyebrow muscles, particularly the portion that pulls the eyebrow downwards and medially. This action contributes to facial expressions such as frowning or showing concern. The term itself is derived from the Latin word "supercilium," meaning eyebrow. In anatomical terms, the superciliaris muscle is a component of the orbicularis oculi muscle, a sphincter muscle that encircles the eye socket. It plays a role in involuntary movements of the brow as well as voluntary expressions. Damage or paralysis of the superciliaris muscle can lead to noticeable changes in facial expression, affecting the ability to convey certain emotions. Its function is integral to the complex system of facial musculature that allows for non-verbal communication.
