The caudal human nucleus of the solitary tract (NTS) is composed of 10 subnuclei. The commissural subnucleus spans the midline below the obex, merging rostrally into the medial subnucleus. The other subnuclei of the NTS are best seen just above the obex. The ventrolateral subnucleus contains large, darkly staining neurons. The interstitial subnucleus consists of neurons lying in groups intermingled with the fibers of the tract. The lateral subnucleus is small at caudal levels, merging with the interstitial subnucleus more rostrally. The dorsal subnucleus contains large melanotic neurons and encircles the substantia gelatinosus, a round, cell-poor subnucleus. The ventromedial subnucleus curls around the medial and ventral edge of the tract. The intermediate subnucleus, laying ventrolateral to the dorsal motor nucleus of the vagus, also contains melanotic neurons. The subpostremal subnucleus separates the area postrema from the NTS proper. The medial subnucleus is the largest subnucleus in the caudal NTS, containing medium-sized fusiform neurons. Adoption of a uniform cytoarchitectural map of the caudal NTS will permit more accurate comparisons between human and nonhuman studies.
延髓孤束尾侧核（NTS）由10个亚核组成。连合亚核跨越闩下方的中线，在头端与内侧亚核融合。NTS的其他亚核在闩上方最易观察到。腹外侧亚核含有大的、深染的神经元。中间质亚核由成群的神经元组成，与孤束纤维相互交织。尾侧水平的外侧亚核较小，在头端与中间质亚核融合。背侧亚核含有大的含黑素神经元，环绕着胶状质，胶状质是一个圆形、细胞稀少的亚核。腹内侧亚核围绕着孤束的内侧和腹侧边缘卷曲。中间亚核位于迷走神经背运动核的腹外侧，也含有含黑素神经元。最后区下亚核将最后区与NTS本体分开。内侧亚核是尾侧NTS中最大的亚核，含有中等大小的梭形神经元。采用统一的尾侧NTS细胞构筑图谱将有助于在人类和非人类研究之间进行更准确的比较。
