Influence of immobilisation of limbs in kittens on the morphology of the developing neuromuscular junctions

Immobilisation of limbs in kittens, in which the neuromuscular apparatus is in active growing phase, affects the maturation of the end-plates, which appear smaller and pointed. Longer periods of immobilisation lead to a significant reduction in the surface area of the neuromuscular junctions which were seen to be "V" or "W" shaped.
