电子显微镜结合对人类视网膜薄片的某些组织化学研究，提供了有关占据外界膜和视网膜色素上皮之间细胞间隙的粘液物质的附加信息。霍特利杆和锥体内节的肌样区域含有丰富的与细胞内粘液和蛋白质物质的加工相关的细胞器。这表明感光细胞的这一部分最有可能是粘液基质的来源，视细胞的内节和外节悬浮在其中。如此集中在感光细胞顶端区域的细胞器可能还参与光接收和/或神经冲动的产生和传递所需的细胞内物质的产生。
Electron microscopy combined with certain histochemical studies on thin sections of the human retina has provided additional information concerning the mucinous material that occupies the intercellular space between the outer limiting membrane and the retinal pigment epithelium. The myoid region of the inner segments of hotli rods and cones contains an abundance of organelles associated with the intmcellular elaboration of mucinous and proteinaceous substances. It is suggested that this part of the photoreceptor cells is the most likely source of the mucoid ground substance in which the inner and outer segments of the visual cells are suspended. The organelles that are so concentrated in the apical region of the photoreceptor cells are probably also involved in the production of intracellular materials required for photoreception and/or generation and transmission of nerve impulses.
