|Latin||recessus piriformis, sinus piriformis|
|Gray's||subject #244 1142|
On either side of the laryngeal orifice is a recess, termed the piriform sinus (also piriform recess or piriform fossa), which is bounded medially by the aryepiglottic fold, laterally by the thyroid cartilage and hyothyroid membrane. It is a common place where food can be trapped or if injured (eg., by a fish bone), can give the sensation of food stuck in the throat.
The term "piriform" is also sometimes spelled "pyriform" (as in the diagram on this page.)
