n.神经分布；神经支配
Recently, innervation of the spondylolytic tissue was reported to be one of the sources of low back pain. 近来，神经分布与滑脱组织被报导为是下腰痛疼痛来源之一。
However, because the striated urethral sphincter has similar innervation, patients are exercising this important muscle as well. 由于提肛肌和外括约肌的神经支配类似，所以在收缩提肛肌的同时，外括约肌也得到锻炼。
