Human Nasal Cavity and Paranasal Sinuses Anatomy Diagram #212857 (License: Personal Use)

This historical black-and-white engraving depicts a sagittal cross-section of the human head, focusing on the nasal cavity, ethmoid and maxillary sinuses, inferior and middle turbinates, and the relationship to the upper teeth and palate. Fine hatching illustrates mucosal texture and vascular pathways, while labeled points (a-h) identify key anatomical landmarks such as the nasolacrimal duct, inferior meatus, and alveolar ridge. The illustration reflects pre-modern anatomical understanding but remains valuable for teaching spatial relationships in ENT and dental anatomy.

Used in medical textbooks, online anatomy resources, otolaryngology educational modules, and historical medical illustration archives; serves users seeking foundational knowledge of nasal physiology, sinus drainage, or comparative anatomy.
