NASAL CAVITY | Lumen of nose, separated into left and right portions by nasal septum supported by cartilage, vomer, and perpendicular plate of ethmoid; supported laterally by nasal conchae |
ANTERIER NARES | Nostrils External openings of nasal cavity |
VESTIBULE | Extends from the anterior nares to the inferior meatus Supported by cartilage of septum and ala Lined with skin epidermis (keratinized stratified squamous epithelium) with vibrissae (hairs) |
RESPIRATORY PORTION | Extends from vestibule to posterior nares Supported by bones of septum and nasal conchae, which curve to form meatuses Lined with highly vascular respiratory mucosa (ciliated pseudostratified columnar epithelium) Olfactory epithelium in superior lining |
PARANASAL SINUSES | Four pairs of air-filled spaces within frontal, maxillary, ethmoid, and sphenoid bones of skull Lined with ciliated pseudostratified columnar epithelium Drain into the nasal cavity |
POSTERIOR NARES | Openings from the nasal cavity into the pharynx |
LARYNX | Voice box Extends from laryngopharynx to trachea Supported by nine cartilages connected by muscle and ligaments Lined with mucosa (ciliated pseudostratified columnar epithelium, except epiglottis and vocal folds) |
INFRAGLOTTIC CAVITY | Segment below glottis, between vocal folds and trachea |
VESTIBULAR FOLDS | Superior pair of lateral mucosal folds |
VENTRICLE | Space between the vestibular folds and vocal folds |
