Histological studies on the bucco-pharynx of the milkfish Chanos chanos (Forskal)‎ from the Red Sea

Abstract EN

The mucosal epithelium of buccal and pharynx cavities of the milkfish, Chanos chanos is a stratified one, provided with numerous secretory cells and taste buds.

The formers become more numerous as one passes caudally towards the pharynx while the taste buds show a reverse tendancy .

The epithelium lining the epibrarichial organs is greatly similar to that of pharynx.

The lamellar structure, that is in the entrance canal of these organs can be considered as modified gill filament according to its histological structure.

and the epibranchial organs function principally as accessory to the digestive system .

The vascular's supply to both the core and the mucosa that covers, the rakers makes us believe that thcy are respiratory gill filaments.
