Human Skull Anatomy and Bones

The video tutorial explains the structure of the human skull, which consists of 22 bones: 8 cranial bones and 14 facial bones. The cranial bones protect the brain and include the occipital, sphenoid, ethmoid, frontal, parietal, and temporal bones. The facial bones include the mandible, vomer, maxillae, palatine, nasal, zygomatic, and lacrimal bones. The tutorial also covers the immobility of skull bones due to sutures, the role of ossicles in the ear, and the structure of the nasal cavity. The video concludes with a call to action for viewers to engage with the content.
