parietalnych

Parietalnych is a term that appears to be a grammatical declension in Polish, likely referring to the parietal bones. In anatomy, the parietal bones are two bones in the skull which, when joined together, form the sides and roof of the cranium. They are paired bones, meaning there is one on each side of the head. The parietal bones articulate with several other cranial bones, including the frontal bone anteriorly, the temporal bones inferiorly, the occipital bone posteriorly, and the sphenoid bone medially. The sagittal suture separates the two parietal bones at the midline of the skull. The coronal suture separates the parietal bones from the frontal bone, and the lambdoid suture separates them from the occipital bone. The squamous suture separates them from the temporal bones. These sutures are important landmarks in skull anatomy and are particularly noticeable in infants and children before they fully fuse. The parietal bones protect the underlying brain and play a role in the overall structure and shape of the head. The term "parietalnych" would be used in a Polish context when referring to these bones in a genitive or other case, depending on the grammatical structure of the sentence.
