🔹PARIETAL BONES :
These bones form thes sidesand roof of the skull.
They articulate with each other at the sagittal suture, with the frontal bone at the coronal suture, with the occipital bone at the lambdovidal suture and with the temporal bones at the squamous sutures.
The inner surface is concave and is grooved to accommodate the brain and blood vessels.
The parietal bones are reciprocal skull bones that structure the unrivaled and horizontal dividers of the head. They overlie the parietal flaps of the cerebrum and are covered hastily by the epicranial aponeurosis. The parietal bones are important for the neurocranium, along with the frontal, ethmoid, sphenoid, transient and occipital bones. The majority of each parietal bone structures the calvaria (skull cap), while the leftover more modest part is a segment of the cranial base (basicranium). The capacity of the noggin, and subsequently the parietal bones, is to ensure the basic delicate cerebrum.
The parietal bone is somewhat bended and has a quadrilateral shape. It has two surfaces, four boundaries and four points. The boundaries articulate with the adjoining skull issues that remains to be worked out different cranial stitches. The surfaces contain various hard highlights and spaces that compare to the anatomical constructions lying against the bone, for example, shallow veins of the cerebrum.
