Abstract:
1. The ultrastructure of the synapses in the supraoptic nucleus of the hypothalamus of the rat has been studied with the electron microscope after fixation by glutaraldehyde-osmium tetroxide and double staining with urayl acetate and lead citrate.2. It was found that the morphological features of the synaptic vesicle are closely related to those of the smooth endoplasmic reticulum of the axonal endings.3. On the basis of the facts that the size, form, distribution and arrangement of the synaptic vesicles are similar to the endoplasmic reticulum, it was assumed that both organoids are homologous structures.4. The synaptic vesicles may be mainly derived from the endoplasmic reticulum in tile axonal endings. An other possible way of their may be from the invagination of the surface membrane of the eudings.
