The central cervical nucleus (CCN) in the upper cervical cord of the cat was studied with the Golgi rapid, Golgi Cox, and Golgi Kopsch methods. The majority of the neurones were large, multipolar, with dendrites radiating out from the nucleus dorsolaterally, laterally, and ventrally. Occasionally, small triangular or spindle shaped neurones were seen with dendrites following the rounded countour of the CCN. The axons from the large neurones were mostly directed towards the anterior commissure. Occasionally, the initial part of the axons from the smaller neurones were observed. They gave off collaterals within the CCN. The bulk of afferents came from the dorsal funiculus and spread out to form an afferent plexus around the CCN neurones. A small number of afferents was observed from the lateral funiculus. They were thinner than those from the dorsal funiculus and entered the CCN from its lateral aspect. The afferents from the dorsal funiculus had the same orientation as the dorsolaterally directed dendrites and the lateral funicular afferents the same as the laterally oriented dendrites.
采用高尔基快速法、高尔基-考克斯法和高尔基-科普施法对猫颈髓上段的中央颈核（CCN）进行了研究。大多数神经元体积较大，呈多极形，其树突从细胞核向背外侧、外侧和腹侧呈放射状分布。偶尔可见小的三角形或纺锤形神经元，其树突沿着CCN的圆形轮廓分布。大神经元的轴突大多指向白质前连合。偶尔也能观察到小神经元轴突的起始部分。它们在CCN内发出侧支。大部分传入纤维来自薄束，散开后在CCN神经元周围形成传入神经丛。观察到少量传入纤维来自外侧索。它们比来自薄束的纤维细，从CCN的外侧进入。来自薄束的传入纤维与背外侧方向的树突方向相同，而来自外侧索的传入纤维与外侧方向的树突方向相同。
