[Morphometric characteristics of neuromuscular spindles in hypertrophied skeletal muscle].
Skeletal muscle hypertrophy in young male rats was found to be accompanied by adaptive changes in neuromuscular spindles. The changes consisted in connective capsule thickening, increased diameter of NMS and intrafusal muscle fibers, expanded afferent and efferent nerve terminals, increased microcirculatory bed capacity. The quantitative and qualitative shifts observed in NMS structure are morphologically equivalent to the rise in their functional potential, which forms the basis for the functional changes in conditions of increasing skeletal muscle hypertrophy.
