Question: 1 / 400

What is false regarding parietal bones?

They articulate with the temporal bone

They articulate with the maxilla

They articulate with the frontal bone

They articulate with the ethmoid bone

The statement regarding parietal bones that is false is that they articulate with the ethmoid bone. Parietal bones primarily form the upper sides and roof of the skull and are primarily connected to other bones through sutures.

Parietal bones articulate with the temporal bones, which are located on the lower sides of the skull, through the squamous suture. They also connect with the frontal bone at the coronal suture, which is important for the formation of the forehead. Additionally, although they do not directly articulate with the maxilla, the maxillae are located more anteriorly on the face and do not have a direct sutural connection with the parietal bones.

However, the ethmoid bone is situated at a different position, primarily in the midline of the skull's base, separating the nasal cavity from the brain. It does not make direct contact with the parietal bones, which makes the assertion that parietal bones articulate with the ethmoid bone inaccurate.
