[Stereologic analysis of the human hypoglossal nucleus during the period ranging from the 22nd postovulatory week until birth].
The hypoglossal nucleus consists of the cells of the fourth stage of maturation according to Rakić. However, there are obvious differences and one of them is observable in the degree of staining intensivity of their Nissl bodies and nuclear inclusions. The stereological analysis revealed a constant decreasing of numerical density of the nerve cells nuclei in stages investigated. The decrease of the numerical density was highly significant (p < 0.001), probably due to the tissue growth and the total increase of nucleus i.e. its neuropi. The shrinkage of the tissue must be taken into consideration, too.
