Quantifications in parasympathetic ganglia are not available in literature. The otic ganglia of 9 Wistar rats were studied (thick and semi-thin sections) in order to determine the following quantitative data: ganglionic volume (GV), neuronal volume density (Vv), neuronal cellular surface per cell volume (Sv), and neuronal numerical density (Nv). The results showed (mean .+-. SD): GV = 0.31 .+-. 0.05 mm3, Vv = 39.62 .+-. 12.25%, Sv = 0.169 .+-. 0.056 .mu.m-1 and Nv = 3.84 .times. 10-5 .+-. 1.69 .times. 10-5 .mu.m-3. These determinations provide a basis for comparisons of parasympathetic with synpathetic ganglia.
