Craniofacial Anatomy
Exam Answer Key
Course Introduction
Craniofacial Anatomy focuses on the structural and functional organization of the head, face, and neck in humans. This course explores the bones, muscles, nerves, blood vessels, and soft tissues that comprise the craniofacial complex, emphasizing their developmental origins, spatial relationships, and clinical significance. Through lectures, laboratories, and case studies, students gain a comprehensive understanding of normal craniofacial structure, as well as common congenital and acquired anomalies, providing a solid foundation for further study in dentistry, medicine, and related health sciences.
