How does the frontal bone structure differ between females and males?

• A. Higher and more rounded in females
• B. Lower and flatter in males
• C. Equal in both sexes
• D. More angular in females

Answer: (A)

The frontal bone, which forms the forehead, exhibits certain structural differences between females and males primarily due to the variations in cranial anatomy that are influenced by biological and hormonal factors. In females, the frontal bone tends to be higher and more rounded. This curvature not only contributes to a softer facial contour but also plays a role in the overall aesthetics and morphological characteristics typically associated with female skulls. Research in anthropometry and craniofacial studies supports this observation, indicating that the frontal bone shape in females is generally more rounded and less pronounced, whereas males typically possess a more pronounced brow ridge and a flatter forehead. This distinction can be useful in forensic science for sex determination based on skeletal remains. The incorrect options highlight characteristics that do not align with the established differences observed in cranial anatomy. For instance, a lower and flatter frontal bone is typically associated with male skull structures, making that choice inconsistent with the known anatomical variations. The assertion of equality in both sexes also contradicts anatomical studies, which demonstrate clear sexual dimorphism. Additionally, the characterization of the bone as more angular in females does not align with the rounder and smoother curvature observed in female skulls.
