Model of working limb

This lab will show my interpretation of how a limb works. This materials I used are boards for the bones, plastic bags for the muscles, show string for the neuron, a screw for the joint, and straws as the thick and thin filaments which are shown later. I hope it turns out the way I intended.

Next is the final project. It doesn't look the greatest but it serves the purpose.

This is supposed to be an arm but I didn't have anything for the hand. The bags are the upper arm muscles. The arm does actually move up and down but of course you can't see that in a picture. The neuron tells the arm that it wants to move and while in movement the muscle contracts.

Next I have an example of how the thick and thin filaments contract and relax.

This is when the are in a relaxed state. They are nice and spread out.

This is when the filaments are contracted, they condense and get smaller in size.

My models show how a limb works and is composed and also how filaments work. The part you don't see the process of going through the brain and then contracting. This lab was a little difficult for me beacuse I am not very creative and don't think outside the box very well. I hope that this serves the purpose for this lab. I worked very hard on the idea and how to display everything, even though it doesn't look that good. I have to say that I didn't really have fun doing this lab as I did with some of the other ones.
