摘要: Publisher Summary This chapter surveys the data on quantitative analysis of peroneustibialis neuron pool in cat's lumbar spinal cord. Reconstructions were made a number moto- and interneurons to determine volumes their cell bodies an attempt was find equation that would facilitate estimation these from measurements optical sections through perikarya. The discusses results view available dendritic organization motoneurons, obtain picture parameters motoneurons as complete possible. histogram nerve cells peroneus-tibialis 7th segment showed two peaks, one at 4000 6000 μ 3 , other 24,000 28,000 . 25 % sample PT L7 determined. mean 4 cords 731 cells. Of cells, 575 had volume smaller 156 larger than 16,000 group with consisted mostly motoneurons; formed mainly by interneurons. However, latter contained appreciable small motoneurons.
