2. What Is a Prosthesis?

WHAT IS A PROSTHESIS?
A prosthesis is an artificial
body part that replaces a
missing one. It helps people
move, look, and feel better
after losing a limb or other
part of the body.

3. Life Without a Limb

LIFE WITHOUT A LIMB
Without a limb, simple
things like walking or
writing become very hard.
A prosthesis helps people
do these things again and
live a normal life.

4. The First Prosthetics

THE FIRST PROSTHETICS
The oldest known prosthesis is a
wooden toe from ancient Egypt,
made about 3000 years ago.
Back then, people used simple
wood and metal to replace
missing limbs.

5. The 20th Century

THE 20TH CENTURY
During World War I and II,
many soldiers were losing
arms and legs. This pushed
doctors and engineers to
make better and more
comfortable prosthetics.

6. How Modern Prosthetics Work

HOW MODERN PROSTHETICS WORK
Today's prosthetics use small
motors and sensors to copy
natural movement. They
read signals from muscles
and move almost like a real
arm or leg.

7. Bionic Arms and Hands

BIONIC ARMS AND HANDS
Bionic arms can do very fine
movements — like holding a
pen or picking up a cup. The
most advanced ones are
controlled by the user's
thoughts.

8. Running and Sports

RUNNING AND SPORTS
Special blade prosthetics
let people run fast and
compete in sports. Some
Paralympic athletes with
prosthetic legs run faster
than most healthy people.

9. 3D Printing

3D PRINTING
3D printing makes it possible to
create prosthetics quickly and
cheaply. A prosthetic hand can
now be printed in just a few
hours.

10. Prosthetics for Children

PROSTHETICS FOR CHILDREN
Children grow fast, so they need
new prosthetics often. Thanks to
3D printing, parents can get a
new one without spending a lot
of money.

11. Brain and Nerve Connection

BRAIN AND NERVE CONNECTION
Scientists are working on
prosthetics that connect to the
nervous system. With these, a
person can feel touch, heat, and
pressure through an artificial
hand.

12. Eye and Ear Prosthetics

EYE AND EAR PROSTHETICS
Prosthetics are not only for
arms and legs. Artificial eyes
and hearing implants have
already helped millions of
people see and hear again.

13. Who Makes Prosthetics?

WHO MAKES PROSTHETICS?
Prosthetics are made by a
team of doctors, engineers,
and designers working
together. Each device is made
individually to fit one specific
person perfectly.

14. Why This Matters

WHY THIS MATTERS
A good prosthesis gives people
back their freedom and
confidence. It is not just a
medical device — it changes a
person's whole life.

15. Conclusion

CONCLUSION
Prosthetics show how medicine
and technology can work
together to help people. Every
year they get better, cheaper,
and easier to use.
