[Effect of transverse G loads on leg skeletal muscle innervation in guinea pigs].
Guinea-pigs were exposed to chest-to-back accleration of 8 G for an hour. This exposure brought about significant morphological changes or a primary-reactive pattern in nerve elements of skeletal leg muscles. With time they enhanced: 6 hours and then 3 days after the experiment a small portion (1-1.5%) of nerve fibers underwent fragmentation and degradation. Motor nerve endings showed the highest resistance. The first signs of restitution of changes in the peripheral nervous system were seen 6 days after the exposure. Nerve fibers did not return to the normal 9 days after the beginning of the experiment.
