Abstract

Bipolar nerve cells are situated between and below the ependymal cells of the central canal of the spinal cord of Cyprinus carpio. One of the processes of the neurons ("CSF contacting neurons") passes by between the ependymal cells into the central canal and forms there a characteristic nerve ending in the cerebrospinal fluid ("CSF contacting nerve ending"). These terminals consist of a central body with numerous stereocilia and one kinocilium. We could not observe any direct contact between the CSF contacting nerve endings and Reissner's fibre. The ependymofugal process of the nerve cells is axon-like. In the perikarya of the CSF contacting neurons, dense-core vesicles (diameter 700-1000 Å) are found besides of smooth and rough-surfaced endoplasmic reticulum, free ribosomes, Golgi areas and mitochondria. Axons containing synaptic and granulated vesicles (diameter 700-1000 Å), form synapses with the perikarya and the CSF contacting nerve processes. On the surface of single ependymal cells, atypical cilia could be observed. The comparison of the species studied up to now, shows that the structure of the spinal CSF contacting neurons is principally similar from fishes up to mammals.
