Everyone knows Terry Fox, the man who travelled the world with one leg, but what made his journey possible after he got his leg removed, what gave him the hope to keep going? Good morning/afternoon teachers and classmates, today is the day where you learn about the inspiring technology of prosthetic limbs. Some of you may not even know what a prosthetic is or how it works, but you may have heard of or know about the Paralympics. I see the paralympics as an opportunity for people with prosthetic limbs to show the world that they are not so different, that they can do the same thing as people with natural limbs.
A prosthetic limb is an artificially made substitute for a limb lost through a defect present at birth or caused by an accident,

Chances are you have without even knowing it. Prosthetics work so effectively and look so convincing that you wouldn 't even know someone was wearing one. A prosthetic consists of a number of different parts. There 's the prosthetic limb itself, the socket (the connection or "interface" between the prosthetic limb and the patient 's body), the attachment mechanism, and the control system. There are many different places that people could have a prosthetics, like how some are commonly used to replace damaged joints. The hip, knee and shoulder joints are commonly replaced with prosthetics another popular prosthetic is an arm, the main types of arm prosthetic are categorized as transradial or transhumeral. Some prosthetics attach below the elbow, while others ones attach to the upper arm when the elbow joint is missing. The same rule applies to artificial legs. Some are used to replace a missing leg. And other prosthetics are used to replace parts missing below the knee. But wait there 's one more, the Cosmetic prostheses do not improve function, but are used to improve a person 's appearance after the loss of a body part. These include ocular prostheses -- artificial eyes -- and silicone hands, fingers, feet and toes. People with prosthetic legs can often climb stairs, walk, swim, and run as if h they were using natural limbs, while prosthetic arms and hands have advanced to the point where they give the individual control of all five fingers. If this is what scientists and doctors have accomplished in the past 50 years, it is difficult to imagine how much technology will improve within the
