Comparing the function of the corticospinal system in different species: organizational differences for motor specialization?

abstract：:The extensor of the second digit of the chicken wing (EDII) is a small, fast-twitch muscle susceptible to chicken muscular dystrophy and well suited for correlated studies of the morphology and physiology of identified nerve and muscle fibers. In cross section, the dystrophic EDII shows morphological abnormalities com...
