A histochemical study on the structural differences of motor endplate in the red, white and intermediate muscle fibers of mouse limb muscle

Using double staining method of succinic dehydrogenase and cholinesterase, the structural differences of motor endplate in the red, the white and the intermediate muscle fibers of the mouse limb muscles were observed. The endplate of the white fiber had a large size and complicated interlacing structure. The endplate of the red fiber had a small size, simple and compact structure. The endplate of the intermediate fiber had a medium size and moderately developed structure.
