The upper portion of the pharynx, the nasopharynx, extends from the base of the [[skull]] to the upper surface of the [[soft palate]].<ref>Clinical Head and Neck and Functional Neuroscience Course Notes, 2008-2009, [[Uniformed Services University of the Health Sciences]] School of Medicine, Bethesda, Maryland</ref> It includes the space between the [[choana|internal nares]] and the soft palate and lies above the oral cavity. The [[adenoids]], also known as the pharyngeal tonsils, are [[lymphoid tissue]] structures located in the posterior wall of the nasopharynx. [[Waldeyer's tonsillar ring]] is an annular arrangement of lymphoid tissue in both the nasopharynx and oropharynx. The nasopharynx is lined by [[respiratory epithelium]] that is pseudostratified, columnar, and ciliated.
