Gross morphological and angioarchitectural study of the orol cavity in the Egyptian domesticated ducks anas platy rhynchos domesticus

الملخص EN

The morphology and Angioarchitecture of the Oro-pharynx in the Egyptian domesticated ducks were described.

The present work was carried out on ten apparently healthy domestic ducks of different ages and sexes.

The ducks were anaesthetized, and then injected through the mandibular artery and cranial vena cava by colored red and blue gum milk latex (60 %), respectively to study the arterial supply and venous drainage.

Three specimens were used for the morphological studies ; the oral cavity has palatum and lingua.

Three birds were prepared to study the arterial supply ; the mandibular artery is the main arterial supply of the oral cavity and represents the direct continuation of the external carotid artery.

While the remaining four specimens applied to study the venous drainage ; the two jagular veins terminated in the oral cavity by forming interjagular anastomosis.

The obtained results were photographed, described and discussed with those given by previous authors who performed earlier studies in other species of birds.

The nomenclature used was adopted according to the Nomina Anatomica Avium (1993).
