Where is the piriform recess located?
On either side of the laryngeal orifice in humans is a recess, termed the pyriform sinus (also piriform recess, piriform sinus, piriform fossa, or smuggler’s fossa), which is bounded medially by the aryepiglottic fold, laterally by the thyroid cartilage and thyrohyoid membrane.
What is the piriform recess?
Medical Definition of piriform recess : a small cavity or pocket between the lateral walls of the pharynx on each side and the upper part of the larynx.
What are the potential dangers of the piriform recess?
The branches of the internal laryngeal and inferior laryngeal nerves (continuation of recurrent laryngeal) lie deep to the mucous membrane of the piriform recess. Fish bones and other foreign bodies may pierce the mucous membrane of the recess and cause injury to the internal laryngeal nerve.
Is the piriform fossa in the pharynx or larynx?
The pyriform sinus is located in a posterolateral position in relation to the larynx. It is part of the pharynx. Anatomically, its borders are the thyroid cartilage and thyrohyoid membrane laterally, and the cricoid cartilage and aryepiglottic fold medially.
What is the piriform?
Medical Definition of piriform 1 : having the form of a pear. 2 : of, relating to, or being the part of the cerebral cortex of the piriform lobe that receives primary input from the olfactory bulb the piriform cortex.
Does the piriform recess lies posterior and lateral to the larynx?
The pyriform sinus (also spelled piriform sinus and also known as the pyriform recess, pyriform fossa, and smuggler’s fossa) is the pear-shaped subsite of the hypopharynx located posterolaterally to either side of the laryngeal opening.
What is the role of the piriform fossa?
The piriform fossa forms the bottom part of the pharynx and acts as a pair of side branches of the vocal tract.
What structures are found in piriform recess of larynx?
The piriform recesses (piriform sinuses) are present on either side of the anterolateral wall of the laryngopharynx. They are bounded medially by the aryepiglottic folds and laterally by the thyroid cartilage and thyrohyoid membrane. They are a common place for food to become trapped.
What structures are found in the piriform recess?
What does piriform area do?
The piriform cortex serves a critical role in odor discrimination and perception, synthetic processing of complex odorant mixtures, experience- and state-dependent olfactory sensory gating, short-term odor habituation, and odor memory.
