The supraduodenal portion of the human and canine common bile duct has been shown by indirect immunofluorescent staining with anti-actin sera to contain scattered bundles of smooth muscle arranged predominantly in a longitudinal direction with respect to the axis of the bile duct. Isolated strips of canine common bile duct in vitro can contact in response to stimulation with cholecystokinin. The force of contraction in a longitudinal direction is about three times that in a transverse direction but only 3% of that produced by isolated gallbladder strips. There appears to be a roughly proportional relationship between the amount of muscle demonstrated and the force of contraction in response to cholecystokinin.
通过用抗肌动蛋白血清进行间接免疫荧光染色显示，人和犬的胆总管十二指肠上段含有散在的平滑肌束，这些平滑肌束主要沿胆管轴纵向排列。体外分离的犬胆总管条带在受到胆囊收缩素刺激时会发生收缩。纵向收缩力约为横向收缩力的三倍，但仅为分离的胆囊条带产生的收缩力的3%。所显示的肌肉量与对胆囊收缩素的收缩力之间似乎存在大致成比例的关系。
