SINUS PIRIFORMIS Meaning and
Definition
-
Sinus piriformis refers to the piriform sinus, which is a small, pocket-like space located at the upper part of the throat, behind the tongue. The term "sinus" in this context refers to a cavity or space within the body, while "piriformis" is derived from the Latin word "pirum," meaning pear, due to the sinus' pear-like shape.
The piriform sinus is anatomically positioned between the posterior border of the thyroid cartilage, which forms the Adam's apple, and the thyrohyoid membrane. It can be found on both sides of the throat, forming a symmetrical pair. The sinus piriformis serves as a passage or channel through which air and foods pass on their way to the esophagus.
As part of the upper respiratory and digestive systems, the sinus piriformis plays a crucial role in the process of swallowing. When a person swallows, the larynx moves upward, causing the epiglottis to cover the opening of the larynx to prevent food and liquids from entering the airway. Simultaneously, the piriform sinuses relax and widen, allowing the bolus (a mass of chewed food or liquid) to pass through into the esophagus, eventually reaching the stomach.
Problems may arise with the sinus piriformis, such as inflammation or the accumulation of foreign objects, leading to difficulty swallowing, discomfort, or infections. In such cases, medical attention may be required to diagnose and treat any underlying issues affecting the sinuses.
