Sacral parasympathetic preganglionic neurons innervating the urinary bladder were labelled by applying horseradish peroxidase (HRP) to branches of the pelvic nerve at the neck of the bladder. Bladder preganglionic cells were located primarily in the intermediolateral grey matter of sacral cord segments 1, 2 and 3 and extended from the ventral end of the central canal to the inferior margin of the dorsal horn. Dendrites extended into the dorsolateral funiculus, toward the lateral edge of the dorsal horn, medially beneath the dorsal horn and ventrally within the nucleus. Although a small number of cells were found medially beneath the dorsal horn, it is concluded that the majority of bladder preganglionic neurons occupy a lateral position within the sacral parasympathetic nucleus.
通过将辣根过氧化物酶（HRP）应用于膀胱颈部盆神经的分支，标记支配膀胱的骶副交感神经节前神经元。膀胱节前细胞主要位于骶髓1、2和3节段的中间外侧灰质，从中央管腹侧端延伸至背角下缘。树突向背外侧索延伸，朝向背角外侧缘，在背角内侧下方以及在核内腹侧延伸。尽管在背角内侧下方发现少量细胞，但得出的结论是，大多数膀胱节前神经元在骶副交感神经核内占据外侧位置。
