Furthermore, endoskeleton supports the locomotion and the movements of body parts, while serving as attachment sites for the muscles. Hence, this is the main difference between exoskeleton and endoskeleton. Endoskeleton is what we humans have while exoskeleton is what insects and other arthropods have. Furthermore, the exoskeleton helps in excretion, but endoskeleton does not.
Similarly, another difference between exoskeleton and endoskeleton is that the endoskeleton has bone marrow in the shaft of long bones that helps in making blood cells by the process of endothelial proliferation for the body, while this feature is not present in exoskeleton. Moreover, exoskeleton mostly contains the non-living portions of the body for example scales on fish, hair on most animals, horns, feathers on birds but the inside of this feather to which muscle is attached, the hard part is the endoskeleton and is the living portion of the body which respond to stimuli from the brain.
Hence, this is also an important difference between exoskeleton and endoskeleton. Also, in terms of development, endoskeleton develops from mesoderm or endoderm and exoskeleton from ectoderm. Exoskeleton and endoskeleton differ mainly from each other by the location of the body where it situates. Exoskeleton is present external to the body while endoskeleton is present inside the body. Thus, this is the key difference between exoskeleton and endoskeleton.
Furthermore, they differ from the germ layer from which they derive. Without an endoskeleton, the body would have no shape whatsoever, and for e. The axial skeleton, which is made up of the skull, the rib cage, and the vertebral column, performs the function to protect the fragile organs like the heart, the liver, the kidneys, and the lungs. The appendicular skeleton is made up of the legs and feet, the arm bones, the pelvic girdle, and the shoulder blades, which support the structure and protect the limbs.
What is an Exoskeleton? An exoskeleton is a hard surface that covers the exterior of most animals, known as the invertebrates an animal which lacks a backbone, for e. Just like the Endoskeleton in mammals and other animals, the exoskeleton helps the body by supporting and protecting them. The hard and rigid exoskeleton also provides protection from predatory animals. Exoskeleton: Exoskeleton present outside the body. 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.
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. Some common examples of exoskeleton include scales, calcified shells and chitinous cuticle. Most of the invertebrates or animals that lack backbone have exoskeletons, e.
Insects are the largest group in the animal kingdom that has an exoskeleton made up of a substance called chitin. Their wings are attached to the exoskeleton through muscles. Exoskeleton does not grow with the body. It is shed by the insects several times during their life cycle in a process called molting. Based on the above information, some of the key differences between Endoskeleton and Exoskeleton are as follows:. JavaTpoint offers too many high quality services.
