Axial Skeleton and Cranial Bones

This video tutorial introduces the skeleton, focusing on the axial skeleton, which includes the skull, vertebral column, and thoracic cage. It distinguishes between axial and appendicular skeletons, emphasizing the cranial and facial bones of the skull. The tutorial details the cranial bones, including the frontal, parietal, occipital, and temporal bones, and explains the cranial fossa and sutures connecting these bones.
