• 40% weight reduction relative to controls

muscle

abnormal skeletal muscle morphology ( J:82141 )

skeletal muscle fiber atrophy ( J:82141 )

• skeletal muscle fibers show numerous atrophic fibers

increased variability of skeletal muscle fiber size ( J:82141 )

• skeletal muscle fibers show variation in myofiber size
