Lab 21, Station 2: Skull bones and paranasal sinuses
Lab 21 navigation The skull is divided into two parts: Neurocranium and Viscerocranium. Neurocranium (“brain case”) = Frontal bone, ethmoid, sphenoid, occipital bone, temporal bones (2), and parietal bones (2) The neurocranium has a roof called the calvaria (“skull cap”). Viscerocranium (“facial skeleton”) = Mandible, maxillae (2), zygomatic bones (2), nasal bones (2), lacrimal bones […]

Pterygopalatine fossa
Optional reading Moore’s Clinically Oriented Anatomy, 9th ed., Pterygopalatine fossa section through The bottom line: Pterygopalatine fossa. The pterygopalatine fossa (PPF) is a small, bilateral bony space immediately behind the maxilla. Shaped like an inverted teardrop, it is about the size of a thumbnail. Bony borders Anterior: Posterior surface of maxilla. Posterior: Anterior surface of […]
Root of the neck
Optional reading Moore’s Clinically Oriented Anatomy, 9th ed., Deep structures of neck section through Nerves in root of neck. The root of the neck (base of the neck, cervicothoracic region) is important because it is the region of continuity between the neck and thorax, and the neck and upper limbs. It can be somewhat confusing […]
