The extrinsic innervation of the pelvic organs in neonatal and adult female rats is described. Mainly an in toto acetylcholinesterase method is used; moreover, acetylcholinesterase is demonstrated in sections. The hypogastric plexus is defined as the nerve plexuses caudal to the inferior mesenteric ganglia comprising the uterine cervical ganglia and various smaller ganglia. The origin of the hypogastric plexus is formed by the hypogastric nerves, bundles of nerve fibers from the lumbar and cranial part of the sacral sympathetic trunks, bundles of nerve fibers from the inferior mesenteric ganglia and the pelvic nerves. The origin of the caudal part of the hypogastric plexus is also constituted by the pudendal nerves. The uterine nerves are derived from the ovarian nerves, the uterine cervical ganglia, the hypogastric nerves and the lumbar sympathetic trunks. The nerves to the urinary bladder are derived from the ganglionated nerve plexuses in the mesometrium as well as from the uterine cervical ganglia. The vaginal nerves are derived from the uterine cervical ganglia, the ganglionated nerve plexus in the mesometrium and the pudendal nerve. The rectal nerves are derived from the ganglionated inferior mesenteric plexus, the uterine cervical ganglia and the pudendal nerves. The hypogastric plexus in the rat is in many respects more complex than is known from the literature. These anatomical data are relevant for instance to experimentators who use the pelvic autonomic plexuses in the rat as a model system for the analysis of autonomic neuronal regulation systems in mammals.
描述了新生和成年雌性大鼠盆腔器官的外在神经支配。主要采用整体乙酰胆碱酯酶法；此外，还在切片中显示了乙酰胆碱酯酶。腹下丛被定义为肠系膜下神经节尾侧的神经丛，包括子宫颈神经节和各种较小的神经节。腹下丛的起源由腹下神经、来自腰交感干和骶交感干颅部的神经纤维束、来自肠系膜下神经节的神经纤维束以及盆神经形成。腹下丛尾部的起源也由阴部神经构成。子宫神经源自卵巢神经、子宫颈神经节、腹下神经和腰交感干。膀胱神经源自子宫阔韧带中的神经节神经丛以及子宫颈神经节。阴道神经源自子宫颈神经节、子宫阔韧带中的神经节神经丛和阴部神经。直肠神经源自肠系膜下神经节、子宫颈神经节和阴部神经。大鼠的腹下丛在许多方面比文献中已知的更为复杂。这些解剖学数据例如与将大鼠盆腔自主神经丛用作分析哺乳动物自主神经调节系统的模型系统的实验者相关。
