As specialists, we visualise the pharynx and upper oesophagus with mirrors and a flexible laryngoscope and use rigid endoscopy under anaesthesia, which is the gold standard for investigation of this difficult area.
The pharynx is a long, narrow, almost vertical tube extending dorsally from the mouth. The pharynx dilator muscle extends from the pharynx to the midline of the carapace. Contractions of this muscle dilate the pharynx and draw liquid food in through the mouth from the preoral cavity.
C. elegans is a soil-dwelling nematode that takes in food through a neuromuscular organ, the pharynx .
Some afferent fibres from the epiglottis, palate and pharynx also reach the brainstem via the vagus nerve.
Derived from the Greek for throat, the pharynx is the continuous space behind the nose and the mouth that leads down both to the passage for food and to the passage for air.
Feeding flatworms extend a long pharynx out of their mouths. This tube leads directly into the digestive tract.
The pharynx is connected to the esophagus and the larynx.
Propelled by the contractions that a swallow induces in the pharyngeal musculature, each bolus moves rapidly through the pharynx and the upper esophageal sphincter into the esophagus.
