拇收肌

拇收肌后间隙内独立肌束的形态学研究

The morphologic study on the independent muscle bundles in the posterior adductor pollicis space of hands

尺神经深支均为运动肌支，主要支配小鱼际肌、全部骨间肌、第3和4蚓状肌、拇收肌、拇短屈肌深头。

Profundus nervi ulnaris are muscular branches , which mainly dominates hypothenar muscles , all of the interosseous muscle , third and fourth lumbrical muscles , adductor pollicis muscle and deep head of flexor pollicis brevis muscle .

皮肤进针点与尺神经深支终末段穿拇收肌处的距离是（3.53±0.24）cm。

The depth from the inserted point of the skin to the point where the terminal segment of deep branch of ulnar nerve penetrated through the adductor pollicis muscle , was ( 3.53 ± 0.24 ) cm .

尺神经深支终末段穿拇收肌横头与拇收肌斜头之间入拇收肌后间隙，并在此间隙内发出各肌支。

The terminal segment of deep branch of ulnar nerve drilled through between the transverse head and oblique head of adductor muscle of thumb , and then it came into the posterior space of adductor muscle of thumb .

方法：解剖20个（40侧）成人尸体标本手的拇收肌腱弓，对拇收肌起始部的纤维弓状结构进行观察、测量，对观测结果进行统计学处理。

Methods : The fibrous arch structure of the origin of adductor muscle of thumb was observed and measured on 20 ( 40 sides ) adult cadaveric hand specimens .
