Stuctures identified as lamellar bodies have observed in neurons of the dorsal sensory nucleus of the vagus of the rat medulla oblongata. They consist of stacks of parallel, regularly spaced cisternae which either run straight or curve forming a whorl. Finely textured, electron-dense fibrils are present between adjacent cisternae which are devoid of ribosomes. Ribosomes are attached only to the outermost surface of outer cisternae which are often continous with rough endoplasmic reticulum. Cytochemical studies reveal that these intercisternal fibrils contain abundant amino and imidazole groups as well as carboxyl groups. It is suggested that lamelar bodies arise by close alignment of parallel rough surfaced cisternae with subsqent loss of ribosomes from their surface. In addition, it is inferred that polar groups of intercisternal fibrils play an important role in the regular arrangement of cisternal membranes and in the dissociation of ribosomes from cisternae.
在大鼠延髓迷走神经背侧感觉核的神经元中观察到了被鉴定为板层小体的结构。它们由平行排列、间隔规则的扁平囊堆叠而成，这些扁平囊要么笔直延伸，要么弯曲形成螺旋状。相邻扁平囊之间存在质地细密、电子密度高的原纤维，这些扁平囊不含核糖体。核糖体仅附着于外层扁平囊的最外表面，外层扁平囊常与粗面内质网相连。细胞化学研究表明，这些扁平囊间原纤维含有丰富的氨基、咪唑基以及羧基。有人提出，板层小体是由平行的粗糙表面扁平囊紧密排列并随后从其表面丢失核糖体而形成的。此外，据推断，扁平囊间原纤维的极性基团在扁平囊膜的规则排列以及核糖体与扁平囊的解离过程中起重要作用。
