The Skull

Dr. Morton provides a comprehensive overview of the skull's anatomy, covering the primary bones, sutures, cranial fossae, and the openings for cranial nerves and vessels. The tutorial explains the significance of each structure, including the frontal, zygomatic, maxilla, parietal, temporal, sphenoid, mandible, and occipital bones. It also details the coronal, squamous, lambdoid, and sagittal sutures, as well as the pterion. The cranial fossae are described, highlighting the anterior, middle, and posterior sections. Key openings such as the optic canal, superior orbital fissure, foramen rotundum, foramen ovale, and foramen spinosum are discussed, along with the internal acoustic meatus, jugular foramen, hypoglossal canal, and foramen magnum.
