The anatomical structure and topography of the pelvic plexus were studied in 16 bodies of sheep of both sexes (9 males and 7 females). The studies showed that this plexus originates from sympathetic fibres running from the L3-L7 and S1-S4 ganglia of the lumbosacral section of the sympathetic trunk and parasympathetic fibres (S2-S4) given off by the abdominal branches of the sacral spinal nerves. Distinct individual differences were found in its structure and topography, especially as regards the vegetative ganglia, which are not a constant element of the plexus and show variations. This has provided a basis for the differentiation of two anatomical types of plexus: I, the ganglionic, appearing in 68.7% of specimens and II, the non-ganglionic, present in only 31.2% of specimens.
对16具绵羊尸体（9只雄性和7只雌性）的盆腔神经丛的解剖结构和局部解剖学进行了研究。研究表明，该神经丛起源于来自交感干腰骶段L3-L7和S1-S4神经节的交感纤维，以及骶脊神经腹支发出的副交感纤维（S2-S4）。在其结构和局部解剖学方面发现了明显的个体差异，特别是关于植物性神经节，它不是神经丛的恒定组成部分，存在变异。这为区分两种解剖类型的神经丛提供了依据：I型，神经节型，出现在68.7%的标本中；II型，无神经节型，仅出现在31.2%的标本中。
