摘　　要：采用神经染色和组织化学方法，对扬子鳄泄殖腔的胆碱能神经与肾上腺素能神经分布进行了观察。乙酰胆碱酯酶（ＡＣｈＥ）阳性纤维的分布范围远较肾上腺素能纤维为广，可见于泄殖腔壁各层，而肾上腺素能荧光纤维则多见于血管周围。在泄殖腔壁内见有ＡＣｈＥ阳性神经节。未发现小强荧光细胞（ＳＩＦ），但见荧光纤维与乙酰胆碱能神经节有联系。The distribution of the cloacal nerves of alligator was studied using histochemicalmethod. The AChE positive nerve bundles entered the cloaca mainly with the vessels dividedand rejoined to form plexuses. The rich AChE positive nerve fibers were demonstrated in thecloacal wall. Few adrenergic fibers were only found around the vessels of cloca. SeveralAChE positive ganglia were encountered in the cloacal wall. The neurous of ganglia could bedivided into two types: multiangular and elliptic. Small intense flourecent cells were notseen. The innervation of alligator sinensis, human and several mammals were discussed.
