Rupam Sinha Prabhakar Kumar Aditya Kumar Yousuf Dar


Present study was conducted on esophagus of seven adult Japanese Quail. The oesophagus of Japanese quail was thin walled distensible tube comprised of three distinct segments namely precrop oesophagus (cervical part), crop and postcrop oseophagus
(thoracic part). The crop was in the form of a rounded structure at the level of thoracic inlet, that bulged further ventrally to the right and lied against the pectoral muscles. The postcrop oesophagus was relatively longer, wider and more distensible as compared to precrop oesophagus. The interior of oesophagus presented longitudinal mucosal folds which were prominent in precrop oesophagus and crop as compared to postcrop oesophagus. These muscosal folds were longitudinal in precrop oesophagus and were wavy in crop.
