环颈雉食管和气管的血液供应研究

用血管铸型法和大体解剖学方法对 5只环颈雉的食管和气管的血供进行了解剖学观察 ,结果表明 :分布于食管的动脉有颈总动脉食管支、食管升动脉、颈升皮动脉食管支和食管降动脉 .分布于嗉囊的动脉有嗉囊左、右前动脉和嗉囊左、右后动脉 .分布于气管的动脉有自颈总动脉分出的气管支、气管升动脉和气管降动脉 .分布于肺外支气管的动脉有由颈总动脉发出的支气管支 .回流食管和气管颈段前部的静脉汇入下颌静脉 ;回流食管和气管颈段中后部血液的静脉汇入食管气管静脉干 ;回流食管胸段前部和气管胸段大部血液的静脉汇入食管气管静脉干 ;食管胸段中后部和气管胸段后部以及支气管血液的静脉直接汇入颈静脉根部 .嗉囊左后静脉汇入食管气管静脉干 ,嗉囊左、右前静脉和右后静脉直接注入左颈静脉

Studies on blood supply in esophagus and trachea of ring-necked pheasant (phasianus colchicas strauchi)

The blood supply in the esophagus and trachea of five ring-necked pheasants was studied with vessel cast and gross anatomical methods.The results showed that the esophagus was supplied by the esophageal branch of the common carotid artery,the ascending esophageal artery,the esophageal branch of the ascending cervical cutaneous artery and the descending esophageal artery.The ingluvies was supplied by the cranial and the ingluvies,the caudal sinistral and dextral arteries of the ingluvies.The trachea was supplied by the tracheal branch of the common carotid artery and the ascending and the descending tracheal artery.The bronchi were supplied by the branch of bronchus coming from the common carotid artery.Veins of the cervical cranial segment of the esophagus and trachea were drained into the mandibular vein.Veins of the madial-caudal cervical segment of the esophagus and trachea were drained into the esophatracheal vein trunk.Veins of the cranial thoracal segment of the esophagus and the most thoracal segment of trachea were also drained into the esophagtracheal vein.Veins of the madial-caudal thoracal segment of the esophagus and the caudal thoracal segment of the trachea as well as bronchi were drained into the original segment of the jugular vein.The sinistral caudal vein of the ingluvies was drained into the esophagtracheal vein.Both the sinistral and dextral cranial veins and the dextral caudal vein of the ingluvies were directly drained into the sinistral jugular vein.
