Muscularity is an amalgam of ideas on Tissue Engineering and layered Biological materials combined with imagery and forms from electron micrographs and from scientific illustration and schematics. No chemical specifics this time (though the Adenosine triphophate cycle might be cool for another time)
You can see cells with nuclei in parts of the drawing, while in other parts irregular shapes imply cells, but the inner structures are hidden. The relative flatness evokes different types of micrographs, especially photographs of cells and biological tissue in the transmission electron microscope (TEM). The electrons in the TEM must go through the sample to form an image, but even at 200 KV the electrons can’t go through very much material. They’ll be stopped by less than a micron thickness, even if the material is made up of very light elements. Cells and tissues are bigger and thicker than that, so they’re sliced up into very thin flat sections. Selective staining with heavy elements can help with stability and contrast.
Electron wavelengths and the structures imaged are smaller than the wavelengths of visible light, so there is no real “color”, and images are monochrome. Sometimes different contrast modes can be used to falsely color the image according to composition, for example.
