Histological and histochemical techniques have been employed to determine the structure and autonomic innervation of paraganglia located in the human pelvis. In foetal and early postnatal tissues, paraganglia formed rounded cellular masses which were frequently in company with the autonomic nerves and ganglia of the urinary bladder and other pelvic viscera. The constituent cells contained only small amounts of cholinesterase and were unrelated to enzyme positive autonomic nerves; acetylcholinesterase containing nerves were occasionally observed in the capsule and the fibrous septa of the pelvic paraganglia. In early postnatal specimens, pelvic paraganglia frequently contained single or multiple "pacinian-like" corpuscles, each possessing a central region which was rich in both acetyl and pseudocholinesterase. These structures were rarely observed within autonomic ganglia and were absent 4 1/2 years post partum. By means of a histochemical technique, pelvic paraganglia were found to contain catecholamine which was attributed to the presence of relatively large quantities of noradrenaline. These observations have been discussed with particular reference to the results of other studies on the autonomic innervation of paraganglia.
组织学和组织化学技术已被用于确定位于人类骨盆中的副神经节的结构和自主神经支配。在胎儿和出生后早期的组织中，副神经节形成圆形细胞团块，常与膀胱和其他盆腔脏器的自主神经和神经节相伴。组成细胞仅含有少量胆碱酯酶，与酶阳性的自主神经无关；在盆腔副神经节的被膜和纤维间隔中偶尔观察到含有乙酰胆碱酯酶的神经。在出生后早期标本中，盆腔副神经节常含有单个或多个“类环层小体”，每个小体都有一个富含乙酰胆碱酯酶和假性胆碱酯酶的中心区域。这些结构在自主神经节内很少观察到，产后4年半时不存在。通过组织化学技术发现，盆腔副神经节含有儿茶酚胺，这归因于相对大量去甲肾上腺素的存在。已结合关于副神经节自主神经支配的其他研究结果对这些观察结果进行了讨论。
