犁骨

目的：探讨腭裂与胚鼠的犁骨、Jacobson器官和鼻中隔旁软骨发育的关系。

Objective : The aim of this study was to investigate whether cleft palate is associated with the mal_development of the vomer , Jacobson ′ s organ and para_septal cartilage .

结果表明：驯鹿的犁骨特别发达。

The results were as follows : The vomer of reindeer is very developed .

犁骨沟呈U形，宽而深。

The wide deep vomerine groove showed a " U " type in shape .

颌齿和犁骨齿颗粒状，带形；

Teeth of both jaws and vomer villiform in band ;

犁骨缘至翼上颌缝的距离为40.72mm；

The average distance from the piriform rim to the pterygomaxillary junction was 40.72 mm ;

筛骨垂直板与犁骨之间的生长不平衡是导致先天性鼻中隔偏曲的重要原因，即为主动性偏曲。

The primary reason to cause the congenital septum deviation was the disequilibrium growth between the perpendicular plate and the vomer .

台布一直垂到地板上。②筛骨垂直板的上下径生长大于犁骨，且骨化时间晚，至出生时仍未骨化；

The tablecloth trails on the floor . The perpendicular plate grows faster than vomer along the superior-inferior axis and does not ossify until birth .

口咽腔较大，上下颌，犁骨及腭骨均有细齿带，粘膜由复层鳞状上皮组成，并含有大量黏液细胞和少量杯状细胞；

The buccal-pharynx cavity was large and there were serration cingula on the upper jaw and mandible , vomer and palatine bone ; The mucosa was composed of stratified squamous epithelium with many mucous secretory cells and a few goblet cells in buccal-pharynx cavity ;
