Transmission electron microscope image showing ultrastructural features of skeletal muscle of rats from all groups. A: control group, normal mitochondria and fiber structure. B: HFD group, fat droplet accumulation, damaged, swollen, or fused mitochondria, and disordered fiber arrangement or dysfunctional fiber structure. C: HFD + Pi group, the disordered fiber arrangement improved and less damaged or fusion mitochondria. D: HFD + EA group, mitochondria and fiber structure reversed to normal. White arrows indicate the region of mitochondria.
