Which bone is located on the side of the skull?

The temporal bone is indeed located on the side of the skull. It plays a significant role in protecting the structures of the inner ear and is involved in the formation of the skull's lateral wall. Additionally, the temporal bone provides attachment points for various muscles involved in jaw movement and also houses important features such as the external auditory canal.

The sphenoid bone, while centrally located, does not fit the description of being on the side of the skull, as it is positioned more towards the middle of the skull base. The maxilla, primarily associated with the upper jaw and facial structure, is also not situated on the sides of the skull. The frontal bone is located at the front of the skull and contributes to the forehead area, making it distinctly different from the lateral position of the temporal bone.
