Question

meaning of pharyngeal pouches​

Answer 1

Answer:

Pharyngeal pouches are endodermal out-pockets occurring between the pharyngeal arches in embryological development.

Explanation:

In the embryonic development of vertebrates, pharyngeal pouches form on the endodermal side between the pharyngeal arches. The pharyngeal grooves (or clefts) form the lateral ectodermal surface of the neck region to separate the arches. The pouches line up with the clefts, and these thin segments become gills in fish.

Answer 2

Answer:

A pharyngeal pouch (also called Zenker's diverticulum) is a small bulge or pocket, like a hernia, that occurs in the pharynx. The term 'pharyngeal' refers to the pharynx, the part of your throat that connects the mouth, nose and oesophagus – it runs from behind your nose through to the bottom of your neck.
