The pyriform sinus (also piriform recess, piriform sinus, piriform fossa, or smuggler's fossa) is a small recess on either side of the laryngeal inlet. It is bounded medially by the aryepiglottic fold, and laterally by the thyroid cartilage and thyrohyoid membrane. [1] The fossae are involved in speech.

The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis .
Vallecula is an anatomic term for a crevice, depression, or furrow in something. [1] 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 ).
The laryngeal ventricle, (also called the ventricle of the larynx, laryngeal sinus, or Morgagni's sinus) [1] is a fusiform fossa, situated between the vestibular and vocal folds on either side, and extending nearly their entire length. There is also a sinus of Morgagni in the pharynx.
Among them are the collar of the larynx, the ventricles of Morgagni, the vallecula, and the pyriform sinuses. The larynx is not under conscious control, but whatever produces "ring" can be encouraged indirectly by awareness on the part of the student and the teacher of the sounds which contain it.
