Anatomy of hypopharynx. The pharynx is essentially a muscular tube suspended from the skull base and it is useful to recall the general anatomy of the upper pharynx when thinking about its lowermost segment the hypopharynx. Anatomy of the hypopharynx. The hypopharynx is the area immediately below the posterior of the mouth called the oropharynx and it also is below the area posterior to the nose called the nasopharynx.

The hypopharynx ie laryngopharynx is the portion of the upper aerodigestive tract that extends from the hyoid bone superiorly and extends inferiorly to the inferior aspect of the cricoid cartilage. In front it presents the triangular entrance of the larynx the base of which is directed forward and is formed by the epiglottis while its lateral boundaries are constituted by the aryepiglottic folds. Below the cricoid cartilage the hypopharynx becomes the cervical esophagus.

The hypopharynx is an inferior continuation of the pharynx. Its anterior wall is formed by the posterior part of the tongue. The postcricoid area the posterior pharyngeal wall and the pyriform sinuses fig.

Lying directly above the larynx it represents the site where the pathways of air and food cross each other. It can also however be correctly described as the area immediately above the openings of both the windpipe and the esophagus better known as the food tube. It lies inferior to the epiglottis and extends to the location where this common pathway diverges into the respiratory laryngeal and digestive oesophageal pathways.

The laryngeal part of the pharynx laryngopharynx. It may also spread to the lymph nodes in the neck the carotid artery the tissues around the upper part of the spinal column the lining of the chest cavity and to other parts of the body not shown. It is the part of the throat that connects to the esophagus.

The pyriform sinuses may be imagined as inverted cone shaped outpouchings of the hypopharynx lateral to the larynx. Any use of this image is subject to prevailing copyright. Air from the nasal cavity flows into the larynx and food from the.

Three subsites of the hypopharynx are described being pertinent to localize where squamous cell carcinoma arises. The medial walls of the pyriform sinuses are formed by the aryepiglottic folds. Pars laryngea pharyngis also known as hypopharynx is the caudal part of the pharynx.

Hypopharynx reaches from the hyoid bone to the lower border of the cricoid cartilage where it is continuous with the esophagus. The pharynx the pharynx is called the hypopharynx. In human respiratory system.
