PARIETAL BONES Meaning and
Definition
-
Parietal bones are a pair of flat, curved bones located on the sides and top of the skull. They form the superior and lateral walls of the cranium, enclosing and protecting the brain. The word "parietal" is derived from the Latin term "paries," meaning wall, which aptly describes the function and position of these bones.
Each parietal bone is roughly quadrilateral and combines with the opposite parietal bone at the midline of the skull through the sagittal suture, creating a strong and stable structure. Anteriorly, the parietal bones articulate with the frontal bone through the coronal suture, while posteriorly they meet the occipital bone through the lambdoid suture. Additionally, the parietal bones form part of the temporal and sphenoid bones at their respective sutural junctions.
Due to their position and shape, the parietal bones play a crucial role in protecting the brain from external trauma by forming a sturdy barrier around it. They also provide attachment sites for several muscles that control the movements of the scalp and facial expressions. Moreover, the parietal bones contribute to the formation of the skull's unique contours, influencing the overall appearance and shape of an individual's head.
In summary, the parietal bones are bony structures forming the sides and superior aspect of the skull. Along with other cranial bones, they shield and safeguard the brain, serve as attachment points for muscles, and contribute to the overall shape of the skull.

Etymology of PARIETAL BONES
The word "parietal" originates from the Latin term "paries", which translates to "wall" or "partition". The term was used to refer to the wall of a room or enclosure. When the term was adopted in anatomy, it referred to the bones forming the outer walls of the cranium or skull. Thus, "parietal bones" are the two bones that form the upper sides and roof of the skull.
