Morphometric evaluation of the human cervical motoneurons.
Morphometric analysis of the human cervical large motoneurons in the anterior horn was performed in 7 male cadavers with the help of an image-analyzer and the use of a new tissue preparation method which minimizes shrinkage. This method makes it possible to precisely evaluate the size of cervical motoneurons at each level. Our study revealed a difference in number, average area and total area of the motoneurons between C1-C3 and C4-C7 levels. This results can be of importance in setting standard values for the understanding of morphological and functional correlations.
