Vallecula, va-lek′ū-la, n. a groove or furrow.—adjs.

Each of these surfaces is again subdivided by fissures into smaller lobes, of which the most important are the amygdala or tonsil, which forms the lateral boundary of the anterior part of the vallecula, and the flocculus, which is situated immediately behind the middle peduncle of the cerebellum.

On the superior or tentorial surface of the cerebellum the median or vermiform lobe is a mere elevation, but on its inferior or occipital surface this lobe forms a well-defined process, which lies at the bottom of a deep fossa or vallecula; this fossa is prolonged to the posterior border of the cerebellum, and forms there a deep notch which separates the two hemispheres from each other; in this notch the falx cerebelli is lodged.

In front of the epiglottis are the median and lateral glosso-epiglottic folds passing forwards to the base of the tongue, and enclosing the two valleculæ.
