Used alone, the term "vallecula" usually refers to the epiglottic vallecula.

This is caused by open communication of the posteroinferior fourth ventricle and the cisterna magna through the enlarged vallecula.

Among them are the collar of the larynx, the ventricles of Morgani, the vallecula, and the pyriform sinuses.

Posterior pharyngeal wall, extending from the level of the floor of the vallecula to the level of the cricoarytenoid joints.

The epiglottic vallecula is a depression (vallecula) just behind the root of the tongue between the folds in the throat.

The Yarumal climbing salamander (Bolitoglossa vallecula) is a species of salamander in the Plethodontidae family.

"Vallecula" comes from the Latin word "valles", meaning "valley", and is in the diminutive form of the word, so a vallecula is literally a "little valley".

There are a variety of valleculae in the human body, including one between the hemispheres of the brain, on the inferior surface of the cerebellum, in which the medulla oblongata is located (vallecula of cerebellum).

Tumor invades mucosa of more than one adjacent subsite of supraglottis or glottis or region outside the supraglottis (e.g., mucosa of base of tongue, vallecula, medial wall of pyriform sinus) without fixation of the larynx.

The Macintosh blade is positioned in the vallecula, anterior to the epiglottis, lifting it out of the visual pathway, while the Miller blade is positioned posterior to the epiglottis, trapping it while exposing the glottis and vocal folds.

It is clinically important in performing direct laryngoscopy with a Macintosh laryngoscope blade; the blade tip is placed in the vallecula and moved anteriorly, which causes the hyoepiglottic ligament to pull the epiglottis anteriorly as well and thus expose the glottis.

The anterior wall consists of the base of the tongue and the epiglottic vallecula; the lateral wall is made up of the tonsil, tonsillar fossa, and tonsillar (faucial) pillars; the superior wall consists of the inferior surface of the soft palate and the uvula.
