The disposition of Golgi's reticular system in cells of human sympathetic ganglia is reviewed. The author studies 15 human sympathetic ganglia (3 upper cervical, 4 stellate, 2 thoracic and 6 lumbar), impregnated with reduced silver nitrate after formol fixation. The morphologic figures were divided into six types based, in part, on those described by Cajal when studying the Golgi system of spinal ganglia: in the first type (circumscript) the granulations are located in one of the cell poles; in the second (semilunar) they are disposed in the form of a semi-sphere; in the third (horseshoe) they are located like in the second type but in a more sparse form; in the fourth (circular) the granulations surround completely the nucleus; in the fifth (compact) they are scattered all over the cell; in the last type (oppositional) the granulations are located in two opposite spots. Serial sections of 7 micra were made numbering 35 for each case. The author examined one section out of every 3 and counts 100 elements in each case, finding the following percentages for the 6 considered types: 1) 35.46% ± 4.66; 2) 14.86% ± 3.34; 3) 15.06% ± 3.33; 4) 15.13% ± 2.25; 5) 12.93% ± 4.02; 6) 6.53% ± 2.98. The signification index was established with the Student's formula and the author concludes that the values found bear statistical meaning and are not mere chance results. The author concludes that, in human sympathetic ganglia, when the reduced silver nitrate method with formol fixation is used, the circumscript form is the most frequently found type of Golgi's system disposition.
