Method Abstract:"Triceps surae alpha-motoneurons in cats of different postnatal ages were stained intracellularly with horseradish peroxidase (HRP) and studied light microscopically."
Comments Abstract:"The mean diameter of the cell body grew from 39.6 micrometer at birth to 57.6 micrometer in the adult cat, while the corresponding figures for the intramedullary axon diameters were 2.4 micrometer and 6.7 micrometer." Keywords:neuron,nerve cell,calf,size,width,length
