Which structure gives the form to the eyebrows?

The superciliary arch plays a crucial role in giving form to the eyebrows. This bony prominence is located on the frontal bone, just above the eye sockets, and provides the necessary support and contour for the eyebrow region. The configuration of the superciliary arch helps define the shape and position of the eyebrows, contributing significantly to facial expression and aesthetics.

In contrast, the frontal eminence refers to the rounded elevation on the frontal bone, primarily involved in forming the forehead, and isn't specifically related to eyebrow shape. The incisive fossa is a depression in the anterior part of the maxilla, associated more with dental structures than facial features. The temporal bone, while important for the overall structure of the skull and containing various features essential for hearing and balance, does not influence the form of the eyebrows directly.

Understanding the specific functions of these anatomical structures helps clarify their roles in facial morphology. The superciliary arch is specifically noted for providing the framework that not only supports the eyebrows but also contributes to the overall character of the face.
