Difference Between Endoskeleton And Exoskeleton

Endostructure and Exostructure are the body parts of organisms that consist of a complex network of different parts.

The rigid part that is the internal support of a structure is called the internal structure. It grows from a thick layer of skin and is called a biostructure. Some examples of endoskeleton are cartilage, cartilage, etc.

Difference Between Endoskeleton And Exoskeleton

The hard tissue outside the body that protects the soft tissues and muscles is called the exoskeleton. This grows out of the exoskeleton and is often called an inorganic structure. Some examples of exoskeletons include hair, feathers, scales and horns.

What is Endoskeleton?

The endoskeleton is a system of rigid hard tissues, also known as bone, within the body of an organism. The endothelium supports the structure and protects complex tissues and internal organs.

Many vertebrates (animals with vertebrae or vertebrae) including mammals, reptiles, amphibians, birds and fish have an endoskeleton composed of tissues in the form of cartilage and bone.

The endoskeleton is the internal bones and vertebrae that provide support and protection. The word “endoskeleton” comes from the Greek “endo” meaning “within” or “within”, and “skeletons” meaning “bones”.

The endoskeleton provides the foundation to the body and provides physical strength and support to the animal body and also protects vital organs such as, lungs, heart, brain and kidneys etc. The endoskeleton consists of bones and connective tissue including cartilage, ligaments and tendons.

What is Exoskeleton?

The exoskeleton is a hard tissue that covers the outside of most animals, helping to support and protect the body in the same way that invertebrates (animals without backbones, such as arthropods, molluscs, annelids, and coelenterates) do if they have an internal structure.

The hard, tough exoskeleton also provides protection from predators. In addition, the hydrophobic material of the exoskeleton ensures that it removes moisture from the surface of the animal, thus protecting and acting as a barrier.

The word “exoskeleton” comes from the Greek words “bahir” meaning “outside”, and “skeleton”, meaning “bones”. The exoskeleton supports and protects the animal’s body like an inner inner sleeve. The exoskeleton is a hard shell that protects the cover and protects the animal’s body.

Exoskeletons are found in invertebrates due to the absence of spines. Insects, crustaceans, the shells of some sponges, and many families of shelled molluscs all have exoskeletons.

Chitin is the most important component of the exoskeleton of insects and crustaceans. Exoskeletons are generally rigid and fixed, but may contain joints, fragments or breathing holes (spirals).

The soft intestinal tracts of exoskeletal animals expand with age. However, their exoskeletons do not expand. The outer bones split and fall off when the animal’s thin body becomes too large.

This is called “molding”. The animal’s body then forms new exoskeletons. During the formation of new exoskeletons, the animal faces various threats.

On the other hand, shrimps, crabs, shrimps and snails have exoskeletons that resemble a shell. Calcium carbonate is the main building block of shells. Shelled animals do not shed their shells. As animals expand, their shells round the edges.

  • Endoskeleton

The first and most important function of the internal structure is to protect and support the body. Without the internal fork, the body would have no form, and just as man could not stand on his own.

The axial skeleton, formed by the cranial spine and ribs, serves to preserve delicate organs such as the heart, liver, kidneys, lungs, etc. structure and protection of body parts.

  • Exoskeleton

Exoskeletons consist of tissues that increase the strength and rigidity of exoskeletons. The functions of the exoskeleton are remarkably similar to those of the interior.

It protects the animals from attack by unseen creatures so that their soft internal organs are not damaged. Chitin is an important component of the exoskeleton in insects, which protects them. The different types of exoskeleton are: The Arthropod Cuticle, shell, and molt.
