本研究的目的是确定雪貂气管的神经和神经节的结构。从四个新生的雪貂和三个成年雪貂气管进行乙酰胆碱酯酶活性的组织化学染色，并在其整体作为整体坐骑进行分析。该结构包括一个或两个纵向神经干覆盖在气管肌的后表面，一个密集的神经丛浅表的气管肌，这些纵向神经干互连，和，在前表面上，一个神经丛浅表的粘膜下腺体和位于软骨环之间。此外，深神经丛与气管肌和粘膜下腺体有关。神经节细胞体沿着纵向神经干较大（平均直径±. S.E. = 34.3 .+-. 0.3μ m），通常通过柄附着于神经干，并且松散地聚集成多达38个细胞体的组。相比之下，这些细胞体的表面肌肉和腺丛显着较小（平均直径±。S.E. = 24.2 .+-。0.3μ m），从未通过柄附着，并且紧密地聚集在1至4个细胞体的神经节中。我们得出结论，神经和神经节的雪貂气管构成一个或两个纵向神经干含有神经节与大细胞体，两个浅神经丛含有神经节与小细胞体覆盖的平滑肌和粘膜下腺体，分别和两个深神经丛提供终端神经支配的肌肉和腺体。
The goal of this study was to determine the architecture of the nerves and ganglia of the ferret trachea. Tracheas from four newborn ferrets and three adult ferrets were stained histochemically for acetylcholinesterase activity and analyzed in their entirety as whole mounts. The architecture consisted of one or two longitudinal nerve trunks overlying the posterior surface of the trachealis muscle, a dense plexus of nerves superficial to the trachealis muscle that interconnected these longitudinal nerve trunks, and, on the anterior surface, a plexus superficial to the submucosal glands and located between the cartilaginous rings. In addition, deep neural plexuses were associated with the trachealis muscle and with the submucosal glands. Ganglion cell bodies along the longitudinal nerve trunks were large (mean diameter .+-. S.E. = 34.3 .+-. 0.3 .mu.m), were usually attached to the nerve trunk by a stalk, and were loosely clustered in groups of as many 38 cell bodies. By contrast, those cell bodies of the superficial muscle and gland plexuses were significantly smaller (mean diameter .+-. S.E. = 24.2 .+-. 0.3 .mu.m), were never attached by a stalk, and were tightly clustered in ganglia of one to four cell bodies. We conclude that nerves and ganglia of the ferret trachea constitute one or two longitudinal nerve trunks containing ganglia with large cell bodies, two superficial nerve plexuses containing ganglia with small cell bodies overlying the smooth muscle and submucosal glands, respectively, and two deep nerve plexuses providing the terminal innervation to the muscle and glands.
