Facial Bones and Their Functions in the Human Skull

The video tutorial provides a detailed overview of the facial bones of the skull, distinguishing them from cranial bones. It covers the nasal, maxilla, lacrimal, ethmoid, sphenoid, zygomatic, and mandible bones, explaining their locations and features. The tutorial also discusses the inferior nasal concha, vomer, and palatine bones, emphasizing their roles in the structure of the skull. The video concludes with a summary of the facial bones and encourages further study in the lab.
