Nasal Cavity
|
A chamber lined with tiny hair called cilia. Here air is filtered, heated, and moistened to prepare it for it's journey to the lungs.
|
|
|
Nasopharynx
|
the uppermost of the three regions of the throat (pharynx), situated behind the nasal cavity and extending from the posterior nares to the level above the soft palate. On the posterior wall of the nasopharynx, opposite the posterior nares, are the pharyngeal tonsils. Swollen or enlarged pharyngeal tonsils can fill the space behind the posterior nares and may completely block the passage of air from the nose into the throat

|
|
Oropharynx
|
one of the three anatomic divisions of the pharynx that lies posterior to the mouth and is continuous above with the nasopharynx and below with the laryngopharynx. It extends behind the mouth from the soft palate above to the level of the hyoid bone below and contains the palatine and lingual tonsils
|
|
|
laryngopharynx
|
the portion of the pharynx below the upper edge of the epiglottis, opening into the larynx and esophagus.
|
|
|
adenoids
|
one of two masses of lymphatic tissue situated on the posterior wall of the nasopharynx behind the posterior nares. During childhood these masses often swell and block the passage of air from the nasal cavity into the pharynx, preventing the child from breathing through the nose.
|
|
|
palatine tonsils
|
one of a pair of almond-shaped masses of lymphoid tissue between the palatoglossal and palatopharyngeal arches on each side of the fauces. They are covered with mucous membrane and contain numerous lymph follicles and various crypts.
|
|
|
larynx
|
the organ of voice that is part of the upper air passage connecting the pharynx with the trachea. It accounts for a large bump in the neck called the Adam's apple and is larger in men than in women, although it remains the same size in men and women until puberty. The larynx forms the caudal portion of the anterior wall of the pharynx and is lined with mucous membrane that is continuous with that of the pharynx and the trachea. The larynx extends vertically to the fourth, fifth, and sixth cervical vertebrae and is somewhat higher in women and children. It is composed of three single cartilages and three paired cartilages, all connected by ligaments and moved by various muscles. The single cartilages are the thyroid, cricoid, and epiglottis. The paired cartilages are the arytenoid, corniculate, and cuneiform, which support the vocal folds. Also called voice box
|
|
|
epiglottis
|
the thin, leaf-shaped cartilaginous structure that overhangs the larynx like a lid and prevents food from entering the larynx and the trachea while swallowing
|
|
|
trachea
|
windpipe; the cartilaginous and membranous tube descending from the larynx and branching into the left and right main bronchi
