Which bone forms the anterior part of the skull and forehead?

The frontal bone is the bone that forms the anterior part of the skull and forehead. It plays a crucial role in the structure of the skull by providing the forehead's contour and forming the upper part of the eye sockets. The frontal bone is a single bone in adults and contributes not only to the facial structure but also aids in protecting the brain. Its position at the front of the skull makes it integral to the overall shape and appearance of the head.

The parietal bones, located on the sides and roof of the skull, serve different functions and do not contribute to the forehead. The temporal bones are situated at the sides of the skull and are involved in housing the structures of the ears, while the sphenoid bone is located deeper in the skull, contributing to the base and the sides but not to the forehead region specifically. Thus, identifying the frontal bone as the structure forming the anterior part of the skull is crucial for understanding cranial anatomy.
