Using a silver impregnation technique, mainly in teased material, the pattern of muscle spindle motor innervation was compared between reptilian and marsupial material. It was concluded that, although rare, beta fibers (motor nerve fibers which innervate intra‐ and extrafusal muscle fibers) can also be detected at spindle entry in reptiles and in mammals, but that the occurrence is higher in reptilian material.
