Study Notes
Nasal Cavity
- The nasal cavity consists of the vestibule, olfactory region, and respiratory region.
- The nasal septum separates the nasal cavity into two halves.
Paranasal Sinuses
- The paranasal sinuses include:
- Maxillary sinus
- Frontal sinus
- Sphenoidal sinus
- Anterior ethmoidal sinus
- Middle ethmoidal sinus
- Posterior ethmoidal sinus
- Superior ethmoidal sinus
Nasal Meatus and Nasolacrimal Duct
- The nasal meatus is a passage in the nasal cavity.
- The nasolacrimal duct connects the eye to the nasal cavity.
Pharynx
- The pharynx is divided into three parts:
- Nasopharynx
- Oropharynx
- Laryngopharynx
- The pharynx contains the pharyngeal tonsil (third tonsil or adenoid) and the Eustachian salpinx (auditory tube).
Larynx
- The larynx is located at the level of C3-C6 and performs three main functions:
- Respiratory duct
- Swallowing
- Phonation (voice production)
- The larynx is composed of several cartilages, including:
- Single cartilages: thyroid, epiglottis, and cricoid
- Paired cartilages: arytenoid, corniculate, and cuneiform
- The larynx contains laryngeal muscles and the vestibular fold and vocal fold.
Phonation
- Phonation involves the production of sound through the vibration of the vocal folds.
- The larynx is the source of energy for phonation, using the exhaled air.
- The vocal folds and the cavities of the mouth, nose, and sinuses modify and amplify the sound.
Laryngeal Ventricle
- The laryngeal ventricle is a small cavity between the vestibular and vocal folds.
Sex Differences
- The larynx of males and females differ in size:
- Male: longitudinal diameter 44 mm, transverse diameter 43 mm, sagittal diameter 36 mm, and rima glottidis 23 mm
- Female: longitudinal diameter 36 mm, transverse diameter 41 mm, sagittal diameter 26 mm, and rima glottidis 17 mm
