Exo means "outside" and endo means "inside". A human being has an endoskeleton (interior bones and cartilage) which protects the organs, nerves and blood vessels and has muscles attached to enable movement. A good example of an exoskeleton is that of a beetle or a crab in which the inner parts of the body are soft tissue with muscles, nerves, blood vessels and breathing system attached to the outer shell.

What are the differences between endoskeletons and exoskeletons?
An exoskeleton is where the bones are on the outside of an organism. An example could be a crab, or insect. An endoskeleton is what you and I have, bones inside the body. Exo means outside and endo means inside or within by the way.
What are the disadvantages of a endoskeleton?
Endoskeletons can be relatively heavy, which may limit mobility compared to exoskeletons. They also require a more complex system of muscles and joints to function, potentially making movement less efficient. Additionally, endoskeletons are more vulnerable to damage from external forces, as they are not as protective as external structures. Lastly, growth can pose challenges, as organisms must often undergo molting or significant changes to accommodate their increasing size.
Why are ossicles classified as an endoskeleton?
Ossicles are classified as an endoskeleton because they are internal skeletal structures found in certain organisms, such as echinoderms, that provide support and protection to the body. Unlike exoskeletons, which are external and often made of chitin or calcium carbonate, endoskeletons, including ossicles, are made of mineralized tissue and are located within the body. This internal arrangement allows for greater flexibility and growth, as it can expand with the organism. Additionally, endoskeletons serve as a site for muscle attachment, facilitating movement.
What mammal has an exoskeleton?
No mammals do. The armadillo has heavy exterior scales of bone and horn. The pangolin (scaly anteater) also has plate-like scales made of keratin that act as armor. These are not true exoskeletons, as they do not support the organs of the body.
Do vertebrates have endoskeletons?
yes; endoskeleton of vertebrates may be either bone or cartilage
Do prawns have endoskeletons?
No they do not. They have exoskeletons and thus are invertebrates.
Do hawks have endoskeletons or exoskeletons?
Exoskeletons are usually associated with animals like grasshoppers, crabs, or tortoises – not dogs. dogs have endoskeleton
Do most arthropods have endoskeletons?
Endo = inside. Endoskeletons are skeletons like ours, bones on the inside. Arthropods have EXOskeletons, armour on the outside.All arthropods have segmented bodies with tough exoskeletons made from chitin.
Do insects have endoskeletons?
No, insects have exoskeletons, which are hard, external skeletons that provide support and protection. These exoskeletons are made of a material called chitin.
What are 2 types of skeletal systems?
The main types are endoskeletons and exoskeletons.
How are endoskeletons and exoskeletons alike?
Endoskeletons are located inside an organism. Exoskeletons are located on the outside of an organism, like a shell. Both are used for structure and protection.
What is the difference between animals muscles with endoskeletons and exoskeleton?
In animals with endoskeletons, muscles surround the skeleton. In animals with exoskeletons,the skeleton surrounds the muscles.
How are endo and exoskeletons alike?
no arthropods have endoskeletons, completely different structures nothing like exoskeletons, exoskeletons are outer skeletons made of chitin only found on arthropods, endoskeletons are inner support structures like your skeleton, made of bone and/or cartilage.
What factor makes it possible for animals with endoskeletons to grow larger than animals with exoskeletons?
yes
Are insects vertebrates?
No, insects are invertebrates because they contain exoskeletons, not endoskeletons. no they are invertebrates
Do polar bears have an exoskeleton?
Polar bears have endoskeletons.
Do mammals have exoskeletons?
No. They have endoskeletons (inside bones). The armadillo has heavy exterior scales of bone and horn. The pangolin (scaly anteater) also has plate-like scales made of keratin that act as armor. These are not true exoskeletons.
