Origins and extrinsic pathways of the adrenergic innervation of the guinea-pig trachealis muscle were studied using fluorescence histochemical techniques. Bilateral superior cervical ganglionectomy caused a marked reduction in the adrenergic innervation of the extra-thoracic region, which suggests that these ganglia are a major source of adrenergic innervation to this muscle. Combined anterior and posterior transection of the recurrent laryngeal nerves also caused a marked reduction in the density of adrenergic fibres in the extra-thoracic trachealis muscle. Crushing of these nerves revealed adrenergic fibres running both anteriorly and posteriorly. The majority of these adrenergic nerves were lost after superior cervical ganglionectomy and thus the fibres running in both directions originate in the superior cervical ganglion. Antero-posteriorly directed fibres entered the recurrent laryngeal nerve from the superior cervical ganglion via an anastomosis at the level of the cricoid cartilage, while those running postero-anteriorly entered the recurrent laryngeal nerve posteriorly from the vagus nerve and these adrenergic fibres were lost after cervical vagotomy.
运用荧光组织化学技术研究了豚鼠气管平滑肌肾上腺素能神经支配的起源和外在途径。双侧颈上神经节切除术导致胸外区域肾上腺素能神经支配显著减少，这表明这些神经节是该肌肉肾上腺素能神经支配的主要来源。双侧喉返神经前后联合横断也导致胸外气管平滑肌中肾上腺素能纤维密度显著降低。挤压这些神经可发现肾上腺素能纤维向前和向后走行。大多数这些肾上腺素能神经在颈上神经节切除术后消失，因此双向走行的纤维起源于颈上神经节。前后向走行的纤维通过环状软骨水平的吻合从颈上神经节进入喉返神经，而向后向前走行的纤维从迷走神经后方进入喉返神经，这些肾上腺素能纤维在颈迷走神经切断术后消失。
