This schematic model was developed to help first year health science students understand the relationships between sarcomeres, myofibrils, sarcolemma, T-tubules, and sarcoplasmic reticulum, as well as muscle cell nuclei and the collagen which makes up tendon. The students realise that the structure of a skeletal muscle fibre is simpler than they imagine from looking at textbooks and easier to remember.

This schematic model was developed to help first year health science students understand the relationships between sarcomeres, myofibrils, sarcolemma, T-tubules, and sarcoplasmic reticulum, as well as muscle cell nuclei and the collagen which makes up tendon. The students realise that the structure of a skeletal muscle fibre is simpler than they imagine from looking at textbooks and easier to remember.


Production Information

The model is based around 56 standard 330ml beverage cans. Quite a lot of muscle power used to empty all of them!

Most of the cans were wired together into rows of eight, using galvanised 14-gauge wire (e.g., a 20-meter roll), and custom-made washers cut from 0.5mm thick aluminium sheeting (e.g., a piece 300mm x 900mm). The last set of eight cans was divided into a single can and a set of three and a set of four. The sets of three and four were wired together in the same way as the others.

Tools useful for the above steps include tin snips, drill, cutting pliers, miscellaneous other pliers for twisting a knot in the ends of the wire, pen, a point punch, and hammer.

Once wired up, all the cans were spray painted a solid (e.g., pink) colour. This required quite a lot of specialised paint (metal primer and topcoat) and may be optional depending on how opaque the lace fabric used for sarcoplasmic reticulum is.

The single can was also wrapped with paper printed with the following image of actin and myosin filaments. Printing size was adjusted to suit the length of the can.
