Alternative definition : CDISC: The posterior one third of the tongue behind the terminal sulcus that forms
the anterior aspect of the oro-pharynx.; UBERON: The Posterior tongue, or pharyngeal part, is the part of the tongue behind
the terminal sulcus. At its root, it is directed backward, and connected with the
hyoid bone by the Hyoglossi and Genioglossi muscles and the hyoglossal membrane; with
the epiglottis by three folds (glossoepiglottic) of mucous membrane; with the soft
palate by the glossopalatine arches; and with the pharynx by the Constrictores pharyngis
superiores and the mucous membrane. It is derived primarily from the third pharyngeal
arch. (The second arch has a substantial contribution during fetal development, but
this later atrophies. The fourth arch may also contribute, depending upon how the
boundaries of the tongue are defined.).;
