It is essential to study the osteotomes ,dermatomes ,and neurotomes of the lower limb to understand the extent of this block.求此段话的翻译,其中主要是osteotomes、dermatomes、neurotomes三个单、词不知如何翻译,其字面意思是
It is essential to study the osteotomes ,dermatomes ,and neurotomes of the lower limb to understand the extent of this block.
求此段话的翻译,其中主要是osteotomes、dermatomes、neurotomes三个单、词不知如何翻译,其字面意思是骨凿、手术刀等,但实际上用于此段话中都不合适.

It is essential to study the osteotomes ,dermatomes ,and neurotomes of the lower limb to understand the extent of this block.求此段话的翻译,其中主要是osteotomes、dermatomes、neurotomes三个单、词不知如何翻译,其字面意思是
dermatome 这里是皮区、皮节的意思, 它还有生皮节(中胚层体节的外侧部)、植皮刀之意.皮节说的是皮肤神经节段性分布,指一个背根与其神经节供应的皮肤区,称为一个皮节.
neurotome 指神经管节,体表和内脏之间固定的神经节段
osteotome 骨凿,骨刀 (这里就是指下肢用骨刀)
the extent of this block 神经阻滞的范围
整个句子应该是这样的吧：学习（研究）下肢骨刀的应用、皮节的分布以及下肢神经节段（的现象）对理解这部分（在麻醉中）神经阻滞的范围很有必要.

这三个词是三种神经吧。
