transversus abdominis muscle

In present study , 125 sides of the inguinal regions in the chinese adults were used for the anatomical observation and measuring on the internal oblique muscle , the transversus abdominis muscle , the transversus abdominis aponeurosis layers , and iliopubic tract .

在125侧成人腹股沟区标本上，解剖观察并测量了腹内斜肌、腹横肌、腹横肌腱膜筋膜层和髂耻束。

Step 1 , the space between pararenal fat and transversus abdominis and diaphragmatic muscle was enlarged ;

第1步，游离肾旁脂肪浅面和腹横肌深面、膈肌深面之间的间隙，扩大后腹腔肾部。

Result : The important structures from outside to inside using lateral puncture were medium structures of lumbodorsal fascia ( obliquus externus abdominis , obliquus internus abdominis , transversus abdominis , lumbar quadrate muscle ), deep lamella of lumbodorsal fascia , greater psoas muscle , intervertebra foramina and vertebral canal .

结果：侧路穿刺路径由浅入深的主要结构有腰背筋膜中层结构（腹外斜肌、腹内斜肌、腹横肌、腰方肌）、腰背筋膜深层、腰大肌、椎间孔和椎管。
