The rat nucleus ambiguus (Amb nucleus) is composed mainly of laryngeal and pharyngeal motoneurons, and can be differentiated into three main subdivisions with respect to the morphology, distribution and physiological function of their neurons. The medial parabrachial and Kölliker-Fuse nuclei (MPB/KF), and the lateral nucleus of the solitary tract (SolL) play a modulator role over some of the physiological functions assigned to the Amb nucleus. The location and characteristics of labelled neurons in the MPB/KF, SolL and Amb nuclei have been studied following the simultaneous and bilateral injections of True blue and Diamidino yellow in each of the three subdivisions of the Amb nucleus. All of the identified axonal projections were mainly ipsilateral. Some of the described pathways also have collaterals which connect both sides of the Amb complex.
大鼠疑核（Amb核）主要由喉和咽运动神经元组成，就其神经元的形态、分布和生理功能而言，可分为三个主要亚区。臂旁内侧核和 Kölliker-Fuse核（MPB/KF）以及孤束外侧核（SolL）对赋予Amb核的某些生理功能起调节作用。在Amb核的三个亚区中每一个都同时双侧注射真蓝和双脒基黄后，对MPB/KF、SolL和Amb核中标记神经元的位置和特征进行了研究。所有已确定的轴突投射主要是同侧的。一些所述通路也有连接Amb复合体两侧的侧支。
