The analysis was done on 10 samples of general somatomotor nuclei (GSN) of cranial nerves located in the brain stem, which were colored by the Mallory method. The research was conducted by standard testing system A 100 with the use of the light microscope and 40 x zoom objective. We determined the volume density of vascular net and nerve cells of investigated structures. The obtained values were mutually compared. GSN located in mesencephalon were more significantly vascularized. A part of the oculomotorius nuclei, made of nerve cells, is significantly larger compared with other GSN. The oculomotorius nuclei have equal number of nerve cells and blood vessels, while the number of blood vessels in the other GSN is a significantly larger. Acta Medica Medianae 2006;45(1):33-35.
