鸡气囊的形态学研究

采用解剖剥离法和灌注腐蚀法，对鸡气囊的形态学特征进行了研究。结果表明：鸡有8个气囊，包括单一的颈气囊（伸出脊柱内号状憩室和外管状憩室）、锁骨气囊（伸出正中憩室、前外侧憩室、胸心憩室、胸外憩室）和成对的前胸气囊、后胸气囊、腹气囊（伸出3对肾周憩室、股憩室、闭孔憩室、坐骨憩室）。前胸气囊较后胸气囊大，左腹气囊较右腹气囊大。鸡气囊无明显的性别差异，但气囊在不同的禽种中存在差异。

The Morphologic Study of the Air Sacs in the Chicken

The morphologic characteristic of the air sacs was studied by anatomical dissection and injection - corrosion methods in chickens. The results were as follows： There are eight air sacs in chickens namely, unpaired cervical sac （possessed inner and outer vertebral tubular diverticula）, unpaired clavicular sac （ possessed median diverticula, anterelateral diverticula, cardiacithoracici diverticulum, extrathoracal diverticulum）, paired cranial thoracic and caudal thoracic sacs, and paired abdominal sac （possessed three paired perirenal diverticulum, femoral diverticulum, foramen diverticulum, ischial diverticulum）. The cranial thoracic sac was larger than the caudal thoracic, the left abdominal sac was larger than the right sac. No sex differences were observed among the chicken studied. There were differences in air sacs of different avian kinds.
