The effect of limb immobilization and stretch on the fine structure of the neuromuscular junction in rat muscle.
Limb immobilization of rat plantaris muscle in the stretched position for 3 weeks led to increased postsynaptic areas of junctional folds and clefts per nerve terminals in both type I and type II muscle fibers. In addition, various ultrastructural alterations were evident in both types of end plates.
