The topographic distribution of Nucleus Ambiguus (NA) motor neurons innervating the intrinsic laryngeal musculature in the guinea pig has not been studied previously. We used 25 guinea pigs anaesthetized by Penthrane (Methoxyflurane) inhalation. Horseradish peroxidase type VI (40%) was used. The motor neurons traced are distributed in cellular groups elongated rostro-caudally in a tract of the brain stem situated between a rostral plane compatible with the location of the retrofacial nucleus, and a caudal plane some millimetres below the obex. The motor neurons observed do not exhibit differential morphology in relation to the different muscles studied.
以前尚未研究过豚鼠中支配喉内肌的疑核（NA）运动神经元的地形分布。我们使用了25只通过吸入戊烷（甲氧氟烷）麻醉的豚鼠。使用了VI型辣根过氧化物酶（40%）。追踪到的运动神经元分布在脑干的一个区域内，呈头-尾方向拉长的细胞群，该区域位于与面神经后核位置相符的一个头侧平面和闩下方几毫米处的一个尾侧平面之间。观察到的运动神经元在与所研究的不同肌肉相关方面未表现出形态差异。
