| Abstract | ||||
| The hypobranchial apparatus consists of unpaired median part and two branchial horns. The entoglossal bone is well developed in goose than in chicken. It is the longest bone (34.20 mm) in the latter one among the bones of the median part. The range of the movement of the articulation of the above bone with the rostral basibranchial bone is higher in goose than in chicken depending upon the type of the synovial joint. The rostral basibranchial bone is narrow in the middle in chicken, but in goose it decreases in width caudalwards. The branchial horns are relatively short in both examined species. Therefore their tongue are non-protrusible. The degree of divergance of these horns is higher in chicken than in goose basing on the shape of the Lower beak. | ||||
