摘  要:目的:探讨膀胱肌内神经分支分布。方法:采用Sihler’s肌内神经染色、HE染色法研究犬膀胱。结果:犬膀胱呈球形,肌纤维呈编织状分布。膀胱底两侧均可见一神经干与动脉伴行形成血管神经束。两侧神经干在入膀胱前分出外侧支和内侧支。外侧支走行于输尿管外侧,内侧支在输尿管内侧与膀胱动脉伴行,它们在输尿管膀胱连接处发出数支次级分支进入膀胱。外侧支的分支与内侧支的分支于输尿管前上方有吻合,外侧支有一返支分布到输尿管。内侧支较细的分支分布于膀胱三角区及膀胱颈部。内、外侧支在膀胱壁内的分布,呈树枝样,沿膀胱纵轴走行,并以壁内神经节为纽带,交织成网状。左侧神经支明显多于右侧。结论:Sihler’s肌内神经染色法也可用于平滑肌肌内神经分布的研究;支配犬膀胱的神经与动脉伴行;神经入膀胱处分支较密集,以壁内神经节为纽带,交织成网状;呈左侧优势分布;有分支分布于输尿管下段。Objective: To investigate the relationship between intramuscular innervation and the function in bladder. Methods: The modified sihler's and HE teehniche were used for dog's bladder. Results: Dog's bladder,ball-shaped,which its mucsular fibres distribute like a basket-weave. There is a trunk of nerve separately accompanies artery on both sides of the fundus of bladder. Two trunks give out two primary branches respectivly before they enter into the bladder (The lateral's and The medila's ). The lateral's along the ureter in lateral side,the medial's is close to bladder's artery in ureter's medial side. They give out some secondly branches to bladder at the UBJ. There is a recurrent branch of the lateral's to ureter ,other branches anastomy with the branches of the medial's and over ureter anteriorly and superiorly. The thinner branches of the medial's distribute to the neck and fundus of bladder. The branches of the mediat's and the lateral's, like a tree's twig, which travel along the longitudinal axis of bladder and interlace like a net with intramural ganglion as a link. The left branches gain dominance in number over the right's. Conclusions.. Sihler's technique can be used for the research of the intramuscular nervation. The nerve which dominate the bladder accompanies artery , interlace like a net . The branches are intensive after enter bladder with the intramuscular ganglion as ligament. The left branches gain dominance . Some branches supply the inferior segment of ureter.
