The differences of neuromuscular junctions (NMJs) between different muscle fibers had been examined with scanning electron microscopy and analyzed morphometrically. The anterior and posterior latissimus dorsi muscles of the @entity12128 were compared. The former consisted exclusively of slow tonic fibers and the latter of fast twitch fibers. The former had numerous, small NMJs. The @entity308 were small in number. The latter had a large NMJ. The @entity308 were large in number, and subsynaptic folds were found. The extensor digitorum longus and soleus muscles in the @entity35 were also compared. The former consisted mostly of fast twitch fibers whereas the latter consisted of slow twitch fibers (75%) and fast twitch fibers (25%). NMJ of slow twitch fiber was small and the subsynaptic folds had sparse, @entity558 . NMJ of fast twitch fiber was large and the subsynaptic folds had numerous, wide and slit-like openings.
