Biomech - PROSTHETIC LIMBS
[Samus has been busy gathering her notes Biomech has TOTALLY BEEN TAUGHT SO FAR IN SPIRIT and this TOTALLY BACKDATED TO THURSDAY and waits for students/bothersome lurking faculty to filter in/take attendance before starting her thrilling lecture.] Okay. You may remember from last class I mentioned we are going to start learning more about prosthetic limbs and bio-robotics.
Today I'm going to cover basic prosthetics and then we're going to work on a project for the next few weeks.
[TIME FOR NOTES I hope you kids are good at taking them because here goes Samus writing them down on the board and she hopes you are not staring at her ass like all her other classes. 8C]
An artificial limb is a type of prosthesis that replaces a missing extremity, such as arms or legs but with advancements in technology it's not limited to just that. The type of artificial limb used is determined largely by the extent of an amputation or loss and location of the missing extremity. Artificial limbs may be needed for a variety of reasons, including disease, accidents, and congenital defects. A congenital defect can create the need for an artificial limb when a person is born with a missing or damaged limb. Industrial, vehicular, and... war related accidents are the leading cause of amputations. Also chronic stupid is a major contributing factor.
They can be as simple as a wooden peg leg or as complex as a completely articulate hand with natural skin, muscle and even nerve tissue grafted in. There are four main types of artificial limbs. [She writes these on the board and this is probably the part of class you can get away with not paying attention. B| ] Transtibial, Transfemoral, transradial, and transhumeral prostheses. The type of prosthesis depends on what part of the limb is missing. Transtibial prosthesis is an artificial limb that replaces a leg missing below the knee. Transfemoral; above the knee. Transradial; an arm missing below the elbow. Transhumeral; an arm missing above the elbow.
Hopefully in a fighting school like this no one will need to walk away with any prosthetic limbs except for the transradial one we'll be making in class.Who am I kidding?
[Now the board reads in shiny bold font PROJECT]
Since we... don't exactly want to go cutting off any limbs to make these work our project is going to be for a transradial myoelectric limb that attaches to the shoulder and is operated by converting muscle movements to electrical signals, while your real arm hangs limp to your side. I would highly recommend using a chest-strap suspension to hold it in place.
Like this,
If you're successful in your design you can activate and compeltely control your prosthetic limb entirely by biscapular abduction.... or... flexing your arm and chest muscles, in laymen's terms.
As I mentioned, advancements inalien technology have made prosthetic limbs more functional and detailed than ever before. They can be made from carbon fiber which is lightweight and incredibly durable, or other plastics or even wood or metal. You are granted... some creative liberties with this. Just keep in mind your passing grade will be determined how well you build additional pylons it beats my arm in an arm wrestling match, as I'll be working along side you in class.
If you think you can do this project on your own that's just fine. Just remember great minds think alike and you might have more success working with someone else. Or... more success working alone.
[She is going to sit at her desk and otherwise doodle up some blue prints herself.]
You are free to get in groups and discuss amongst yourselves. The last hour of class you can use to start on your research; utilize the library or you can ask me questions. Next class I would highly advise getting a completed blue print done because after that we'll bring in materials and start to build them.
That said... any questions?

Actually no, thousands of tiny Ganondorfs will burst forth and make him teen pregnant and THAT forces him to Falcon Punch himself causing complete impotence in his manly organ, Falcon committing suicide because of Erectile Dysfunction.
