Synapses of a typical form, with synaptic vesicles of 30 to 45 mµ diameter, on one side of a synaptic cleft of 10 to 12 mfx, are found near the bases of the long ciliated cells which make up the comb plates. The side containing the vesicles is interpreted as a section of a nerve fibre terminal in contact with the ciliated cell. Occasionally nerve-cell bodies, identified by similar vesicles, are encountered. These nerves are probably ramifications of the ectodermal nerve net which...[Show more]
