What is Endoskeleton 4. Similarities Between Exoskeleton and Endoskeleton 5. Exoskeleton is an external shell-like structure that is present outside the body of an animal. It is mainly a non-living structure derived from the ectoderm.
The fossil record of mineralized exoskeleton came to light around million years ago. It is very resistant, rigid, somewhat brittle and hard structure that has several specific roles to play. Exoskeleton mainly helps in excreting waste products produced inside the body of an animal or an anthropoda.
Furthermore, it supports the movement and safety of inner softer organs. Not only that, but exoskeleton also involves sensing and feeding. In simple language, it is called a shell. Organisms like snails, crabs, lobsters, shellfish cockroaches, crustaceans and insects like grasshoppers have an exoskeleton and some animals like tortoise have both endoskeleton and exoskeleton. Endoskeleton is the mineralized tissue that gives support to the internal structure of an animal. Endoskeleton: Endoskeleton is found in vertebrates.
Exoskeleton: Endoskeleton is found in arthropods. Endoskeleton: Endoskeleton is made up of bones and cartilages. Exoskeleton: Exoskeleton is made up of chitin or calcium compounds.
Endoskeleton: Endoskeleton is a living structure. Exoskeleton: Exoskeleton is a non-living structure. Endoskeleton: Endoskeleton develops from the endoderm. Exoskeleton: Exoskeleton develops from the ectoderm. Endoskeleton: Endoskeleton grows as the body grows. Exoskeleton: Exoskeleton does not grow with the body. So, it has to be shed over time. Endoskeleton: Endoskeleton is more flexible than the exoskeleton.
Endoskeleton: Endoskeleton provides structures for the attachment of muscles. Exoskeleton: The wings of insects are attached to the exoskeleton through muscles. Endoskeleton and exoskeleton are two types of hard structures in animals that provide structural support. Endoskeleton is an internal skeleton made up of calcium phosphate.
It can be internal endoskeleton or external exoskeleton. Some living organisms have an endoskeleton, some have an exoskeleton and some have both. Let us see how an endoskeleton differs from exoskeleton! It is an internal skeleton present inside the body of a living organism, e.
All vertebrates like birds, fish, reptiles, amphibians and mammalians have an endoskeleton. The endoskeleton is the internal support system that provides structural support and protection to the internal organs and aids in the movement and locomotion. Furthermore, it also provides sites for the attachment of muscles and thus can transmit the forces to the muscles.
The endoskeleton mainly comprises bones and cartilage. In some organisms like cartilaginous fishes, it is exclusively made up of cartilage. Bones are made up of bone cells known as osteoblasts and they form joints to articulate with each other. A bone is attached to another bone by ligament and muscles are attached to bones by tendons.
The exoskeleton is the external skeleton that exists on the outside of an organism. It is the hard outer coating that provides support to the body and protects the muscles and soft tissues or organs of the body. It also protects the animal from predators and harsh environment. Exoskeleton develops from the ectoderm.
An endoskeleton is found in chordates such as vertebrates while an exoskeleton is found in arthropods and some molluscs. Difference between Endoskeleton and Exoskeleton.

You agree that we have no liability for any damages. Definition of Endoskeleton: An endoskeleton is a skeleton that is found on the inside of the body of an animal. Development of Endoskeleton: The endoskeleton of chordates develops from mesodermal tissue during embryonic development. Support and movement: The bony skeleton has allowed vertebrate animals to grow large in size, since it provides enough support to hold considerable weight.
Protection: An endoskeleton of bone protects animals from predators by enabling muscle attachment. Repair and replacement: Bones that break take a long time to heal.
