Size frequency histogram of PSA-NCAM immunoreactive neurons in human trigeminal ganglion from an adult subject (case 5). Cells present in 6 sections were measured. x-Axis values represent the mean cell diameters expressed in μm; y-axis reports values of relative percent frequency. Curve superimposed on the histogram represent the theoretical normal distribution.
