摘要
中国鹅躯干骼由颈部骨骼、胸部骨骼、腰荐部骨骼和尾部骨骼组成.颈部有17～18枚颈椎,连接成“乙”状弯曲,其中第8至第11颈椎的椎体最长,第2至第5颈椎和第15至第16颈椎椎体有典型的腹嵴,第6至第14颈椎腹嵴有血管沟.胸部有9枚或10枚胸椎,后3枚胸椎参与形成腰荐骨,肋骨有明显的腹嵴(龙骨).腰荐骨由最后3枚胸椎、13～16枚腰椎和荐椎愈合而成,横突愈合成棚状.尾部有7～8枚尾椎,均游离存在.
There are 17 or 18 cervical vertebrae in the Chinese goose,which form an S-shaped curva- ture.Among the cervical vertebrae,the vertebral body of the eighth to eleventh is the longest. There are typical ventral crests in the second to fifth and the fifteenth to sixteenth vertebrae.There are sucui vasculosi in the ventral crest of the sixth to fourteenth cervical vertebrae.There are 9 or 10 thoracie vertebrae in the geese.The seventh to ninth thoracie vertebrae commingle with the lumbarsacrum.The lumbarsacrum is composed of the last three thoracie vertebrae,the thir- teenth to sixteen lumbar vertebrae and sacrum vertebrae,where transverse processes commingle and form a shed shape.
