Why Do Prosthetic Limbs Feel Way Heavier Than Biological Ones?

The video explains why we don't feel the weight of our own bodies due to the skeletal system and mechanoreceptors. It discusses the challenges of prosthetic limbs, which often feel heavier than biological ones. Engineers are working on solutions like osseointegration, where prosthetics are connected to the skeleton, improving functionality and comfort. This technique, though promising, has drawbacks such as infection risks. The video highlights the evolution of osseointegration from dental implants to prosthetic limbs, emphasizing its potential to enhance prosthetic design.

Why do prosthetic limbs often feel heavier than biological limbs?

• They are made of denser materials.

• They are not connected to the skeleton.

• They are larger in size.

• They have more mechanoreceptors.

What is a major limitation of using harnesses to attach prosthetic limbs?

• They are difficult to adjust.

• They cause skin irritation.

• They limit the range of motion.

• They are too expensive.

What is osseointegration?

• A method to reduce the weight of prosthetics.

• A technique where bones grow into foreign materials.

• A way to improve muscle strength.

• A process to enhance skin sensitivity.

What material is commonly used in osseointegration for its biocompatibility?

• Steel

• Titanium

• Copper

• Aluminum

What is a potential risk associated with osseointegration?

• Open wound leading to infection.

• Limited range of motion.

• Reduced sensitivity in the limb.

• Increased weight of the prosthetic.
