Age differences in morphology of reinnervation of partially denervated mouse muscle.


The effect of age on the ability of motor neurons to develop and maintain an enlarged total axonal and synaptic volume was compared in soleus muscles of 5-8-month and 25-30-month mice, 30-120 d after partial denervation. Before and after partial denervation (transection of the L5 root), the total number of muscle fibers was the same in all muscles. However… (More)
