Most of us put little thought into the muscles that control the movement of the eye. They just work. Researchers here ask the interesting question: why are these extraocular muscles so resilient? Why does their function decline so little with age, when other muscles throughout the body lose strength and mass, leading ultimately to sarcopenia? There is no complete answer to this question, but it is suggested here that this resilience might have something to do with the fact that the extraocular muscles are much more heavily innervated than other muscles in the body. That in turn might direct a greater focus towards the effects of aging on neuromuscular junctions and consequent loss of innervation in muscles elsewhere in the body. This loss of …
