Hypopharynx

The hypopharynx (from the Greek; ὑπό ( hypό ) = bottom, underneath and φάρυγξ ( Phárygx ) = throat, pharynx ) is an area in the head and neck of animals and humans. In mammals hypopharynx or laryngopharynx denotes the lowest part of the throat ( the pharynx ) of the upper edge of the epiglottis to the upper esophageal sphincter and an imaginary line at the level of the cricoid cartilage of the larynx ( larynx ). The hypopharynx is divided into three districts: the piriform sinus, and Hypopharynxhinterwand Postkrikoidregion.

In insects, the hypopharynx is an appendix of the head capsule, which attaches below the mouth opening. This is not about a real mouth tool, because it was not created from the former extremities. The hypopharynx is originally a membranous structure that can be moved like a tongue, for this reason it is often referred to as a lingua ( tongue). Moves this structure is over basal muscle, which attaches to Chitinvorsprüngen of the hypopharynx, called Basalskleriten. The hypopharynx divides the mouth due to its location in a front mouth and a rear area where the lead Labialdrüsen. As the mouthparts mandibles, maxillae and labium is transformed in different insect groups, such as in a piercing bristle or parts of a suction nozzle and the hypopharynx. Opposite him at the top of the mouth is the nasopharynx.
