Abstract

The fine structure of the cuneate nucleus of the monkey (Macaca fascicularis) has been studied. The neurons were classified into three groups according to their nuclear morphology, the arrangement of the rough endoplasmic reticulum (RER) and the appearance of the Golgi complexes. Group I neurons had a regular nucleus and contained abundant cytoplasm in which were found well-developed RER and Golgi complexes. Group II neurons had a slightly irregular nucleus and a variable arrangement of the RER and Golgi complexes. Group III neurons were characterized by a deeply indented nucleus, and scanty cytoplasm in which the cytoplasmic organelles were poorly developed. Group II neurons were the most commonly encountered while Group I neurons were the rarest. Axon terminals contained either round of flattened vesicles. Axon terminals and dendrites commonly formed synaptic complexes. In one type the axon terminal, containing round vesicles, formed the central element, which is presynaptic to the dendrites surrounding it; in addition it is postsynaptic to axon terminals containing flattened vesicles. In another type a large dendrite formed the central element which is postsynaptic to axon terminals containing round or flattened vesicles.

摘要

对猕猴（食蟹猴）楔状核的精细结构进行了研究。根据神经元的核形态、粗面内质网（RER）的排列以及高尔基体的外观，将神经元分为三组。I组神经元具有规则的细胞核，含有丰富的细胞质，其中有发育良好的RER和高尔基体。II组神经元的细胞核略有不规则，RER和高尔基体的排列可变。III组神经元的特征是细胞核有深深的凹陷，细胞质稀少，其中的细胞器发育不良。II组神经元最为常见，而I组神经元最为罕见。轴突终末含有圆形或扁平囊泡。轴突终末和树突通常形成突触复合体。在一种类型中，含有圆形囊泡的轴突终末形成中央成分，它对周围的树突是突触前的；此外，它对含有扁平囊泡的轴突终末是突触后的。在另一种类型中，一个大的树突形成中央成分，它对含有圆形或扁平囊泡的轴突终末是突触后的。
