The objective of the current study was to present baseline data on the morphology and surface architecture of the oviduct in adult female Balady duck grossly and by using scanning electron microscope (SEM). Fifteen apparently healthy adult female Balady ducks were used which weighted (2-4 kg). Two birds were formalized while the other birds were used in the fresh state for dissection then careful evisceration of the oviduct. For SEM five of the latter were used immediately after immersion in saline. Our data anatomically revealed that infundibulum had funnel and tubular parts, magnum was highly convoluted pale white or creamy color, less convoluted isthmus, dilated uterus and S-shape spiral vagina. The inner wall of the duct contains longitudinal folds in the first four parts while the vagina showed transverse thick folds. color of the mucosa was reddish in infundibulum, magnum and isthmus while greenish brown in color in the uterus and whitish yellow in the vagina. SEM showed primary and secondary folds allover the oviduct which became more thicker in the uterus and carrying tertiary folds in the vagina.

The complex anatomical composition of the brain makes its physical exploration difficult, and it requires introduction of a high definitive diagnostic technique. Computed tomography (CT) is characterized by a high resolution and discrimination of the soft tissue (Abdel

The aim of the present work was to describe the way of creating chosen interactive and animated three-dimensional anatomic virtual models of particular parts of birds' skeleton. These models can be used for teaching purposes in anatomy courses to assist veterinary students, and veterinarians to know the different structures of birds' bones without dissection. We used available multimedia technologies to develop a simple computer program for visualization and annotation of threedimensional duck skeleton. The entire program involves three-dimensional realistic objects, description texts, and images, in addition to quizzes for users' selfassessment. Addressing the anatomical structures made the program more useful to promote knowledge, enhance and facilitate teaching and learning of birds' osteology for veterinary students.

The domestic geese (Anser anser domesticus) are medium-sized birds that belong phylogenetically to subfamily Anserinae of Anatidae family (geese and ducks) in Anseriformes order of the class Aves (Baumel et al. 1993; Hugo 2002). There are about 96 breeds of domestic geese recognized around the world and it is thought that the geese were domesticated in Egypt about 3000 years ago or earlier (Hugo 2002). Commercially since ancient times, geese are bred for their meat, eggs, down and feathers. In birds, due to the lack of the soft palate and glossopalatine folds, a combined cavity of the mouth and pharynx is referred to as the oropharynx that extends from the anterior tip of the beaks to the
