What is an exoskeleton for humans?
An exoskeleton, as the name suggests, is
an external frame that can be worn to support the body
, either to help a person overcome an injury or to enhance their biological capacities. Powered by a system of electric motors, the frame gives limbs extra movement, strength and endurance.
Do humans have endoskeleton?
Humans, of course, have endoskeletons
. But sometimes, neurological conditions and injuries limit the mobility of the body, rendering the human musculoskeletal network almost redundant. Robotic exoskeletons have emerged in the past decade as a solution for people who are unable to move on their own.
What are advantages of endoskeleton?
An important advantage of an endoskeleton over an exoskeleton is that the
endoskeleton provides more structural support
. Endoskeletons hold inner organs, tissues, and systems together easily. This short article about biology can be made longer. You can help Wikipedia by adding to it.
What is exoskeleton made of?
The exoskeleton is composed of
a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer, the procuticle
. In most terrestrial arthropods, such as insects and spiders, the epicuticle contains waxes that aid in reducing evaporative water loss.
