The Nasal Cavity: A Complex Anatomical Framework
The nasal cavity represents one of the most intricate and functionally diverse regions of human anatomy, featuring multiple bones and cartilages that form the foundation of our respiratory and olfactory systems. This detailed sagittal illustration demonstrates the complex arrangement of bones that create the nasal cavity’s structure, highlighting their crucial roles in breathing, smell, and facial development.
Essential Components of Nasal Cavity Anatomy
Cribriform Plate The cribriform plate is a perforated bone plate of the ethmoid bone that forms the roof of the nasal cavity. This delicate structure allows passage for olfactory nerve fibers and is crucial for our sense of smell.

Perpendicular Plate of Ethmoid Bone This vertical extension of the ethmoid bone forms part of the nasal septum. It provides essential support for the nasal cavity structure and helps maintain proper airflow.
Sella Turcica The sella turcica is a saddle-shaped depression in the sphenoid bone. This important structure houses the pituitary gland and serves as a crucial landmark in skull base anatomy.
Quadrangual Septal Cartilage This cartilage forms the anterior portion of the nasal septum. It provides flexibility and support to the nose while maintaining proper airway separation.
Anterior Nasal Spine The anterior nasal spine projects forward from the maxilla. This bony projection provides attachment for nasal cartilages and influences nasal tip projection.

Premaxilla Bone The premaxilla bone forms the anterior portion of the upper jaw. This bone supports the upper incisor teeth and contributes to facial development.
Sphenoid Sinus The sphenoid sinus is an air-filled cavity within the sphenoid bone. It helps reduce skull weight and contributes to voice resonance.
Vomer The vomer is a thin, flat bone that forms the posterior portion of the nasal septum. It provides crucial support for maintaining nasal cavity separation.
Crest of Palatine Bone The palatine crest helps form the nasal floor and hard palate. This structure provides important support for the nasal cavity architecture.
Crest of Maxillary Bone The maxillary crest contributes to the lateral nasal wall structure. It plays a vital role in supporting nasal cavity integrity and airflow dynamics.
