n.神經分布；神經支配

Recently, innervation of the spondylolytic tissue was reported to be one of the sources of low back pain. 近來，神經分布與滑脫組織被報導為是下腰痛疼痛來源之一。

However, because the striated urethral sphincter has similar innervation, patients are exercising this important muscle as well. 由于提肛肌和外括約肌的神經支配類似，所以在收縮提肛肌的同時，外括約肌也得到鍛煉。
