C) The superciliary arch is a type of dental structure.
D) The superciliary arch is also called the zygomatic arch.
Answer:
The superciliary arch, or supraorbital ridge, is a bony ridge located above the eye sockets and forms the rounded brow ridges behind the eyebrows, primarily on the frontal bone.
Explanation: The superciliary arch, also known as the supraorbital ridge, is not located on the foot, not a dental structure, nor is it called the zygomatic arch. Instead, it is a bony ridge above the eye sockets. This arch forms part of the frontal bone and is thickened just above the supraorbital margin, creating rounded brow ridges located behind the eyebrows.
These brow ridges vary in size among individuals and are typically more pronounced in males. The superciliary arch serves as an attachment site for facial muscles and is distinct from the zygomatic arch, which is located on the side of the skull, bridging the cheek to the area just above the ear canal and is involved with the function of biting and chewing.
