The two parietal pah-ri -e-tal bones form the sides and roof of the craniumThey are joined at the midline by the sagittal suture and to. Cranial base comprised of six bones. Frontal sphenoid ethmoid occipital parietal and temporal.

These bones articulate with the 1st cervical vertebra. The skull 22 bones is divisible into two parts. 1 the cranium which lodges and protects the brain consists of eight bones Occipital Two Parietals Frontal Two Temporals Sphenoidal Ethmoidal and the skeleton of the face of fourteen Two Nasals Two Maxillae Two Lacrimals Two Zygomatics Two Palatines Two Inferior Nasal Conchae Vomer and Mandible.
