目的提出阴茎脚交叉解剖学命名,初步探讨其在阴茎勃起中的作用. 方法 15具成人尸体阴茎标本.解剖阴茎脚之间的组织,观察进出阴茎海绵体的神经、血管与阴茎脚之间组织的关系. 结果阴茎脚之间存在双侧坐骨海绵体肌的部分肌纤维,以肌和肌腿抵止于阴茎脚下面和外侧面阴茎海绵体白膜.外侧肌纤维较长,部分肌束抵达阴茎海绵体背面并与对侧同名肌的肌束相互交织,被结缔组织包绕.进出阴茎海绵体的神经、血管穿过上述组织. 结论阴茎脚之间存在阴茎脚交叉.阴茎脚交叉是指双侧坐骨海绵体肌的部分肌束抵达阴茎脚,在阴茎海绵体背面与对侧同名肌的肌束相互交织,被结缔组织包绕.进出阴茎海绵体的神经、血管穿过阴茎脚交叉.双侧坐骨海绵体肌可能是通过阴茎脚交叉的内在联系,统一调控阴茎海绵体血液回流,维持阴茎勃起.

Objective Definition Chiasm of crus penis and discuss its possible role in penile erection. Methods Penile samples were acquired from 15 formalin preserved corpses.The structure located among crus penises were observed.The information about the structure located in crus penises with the nerve and blood vessel structure were recorded and analyzed. Results There was a structure of muscle fiber of ischiocavernosus among the crus penises.These muscle fiber through muscle bundle and tendon reach albuginea of cavernous body of the penis.There was long muscle fiber in the lateral surface of crus penises.While the muscle bundles were interlaced with each other with opposite side homonymous muscle and were encased with connective tissue when it reach to the back side of cavernous body of the penis.There were nerves and blood vessels observed in and out of the cavernous body of the penis and through the above structure in the crus penises. Conclusions Chiasm of crus penis was named as a structure of muscle fiber coming from two sides of the ischiocavernosus in crus penises.The structure of Chiasm of crus penis may provide an internal connection for the role of controlling the erection of the penis.
