Morphological Studies of the Skeletal Muscles of Rats During Hypokinesia

摘要

The skeletal musculature of two groups of Wistar strain rats were studied. A group of 60 day old members were kept in individual cells for physiologic immobilization, while the control group was raised under normal conditions. All animals were killed for tests at 450 days. Skeletal muscles of rats kept 390 days immobilized had a lower weight, muscle fiber diameter of m. semitendinosus was smaller in immobilized rats while variability in muscle fiber thickness was greater in the test group. It is found that degenerative processes involved light and dark fibers.
