The skeletal system of the human body provides a fundamental framework for the body and lends it a certain form. It is essential to keep the internal organs safe and to allow for easy mobility throughout the whole body. Two forms of skeletons are known as endoskeletons and exoskeletons, respectively. Endoskeletons make up the structures of just a few living things, while exoskeletons form the structures of the majority.
The endoskeleton may be discovered in the body’s inner workings. It shapes the body and protects its internal organs from harm. It also aids in the body’s ability to go farther. Instead of being housed within the body, the exoskeleton is found on the exterior. It shields the organism from external hazards and assaults by other predators. In addition, it safeguards the environment and the well-being of the occupants.
Endoskeleton Vs. Exoskeleton
The endoskeleton is found within the organism’s body, while the exoskeleton is found on the organism’s external surface. A human body has an endoskeleton that develops together with it from infancy to maturity, while the exoskeleton has to be shed at some point.
Endoskeleton
In biology, an endoskeleton is the skeleton of a live organism that is located deep inside the body. It protects and supports the body’s internal organs. It’s strong enough to maintain the body’s weight without buckling under the strain. It also helps with locomotion and flexibility of the body.
Endoskeletons are found in almost all vertebrates, and they play an important role in many bodily functions. Every part of the body has an endoskeleton. Adulthood is a time of great change for the organism.. Cortical bone (also known as compact bone) and cancellous bone are the other two forms of bones found in the endoskeleton (also known as trabecular bone).
In addition to safeguarding the body and its internal organs, the endoskeleton serves as a structural support for the whole body, aids in mobility and storage of nutrients, and produces bone marrow for the body when it needs it.
Exoskeleton
The term “exoskeleton” refers to an organism’s external skeleton. Provides structural support to the body via the use of a hard outer shell or covering. Additionally, it protects the body’s muscles and interior organs. Additionally, the endoskeleton serves as a defense mechanism against predators or other external hazards.
Muscles are either linked directly to or cross-joined to the interior of the exoskeleton in most creatures that lack a solid structural backbone, such as cockroaches, lobsters, and crabs. Because exoskeletons do not form within the body as endoskeletons do, arthropods must shed their exoskeletons on a regular basis.
It is common for exoskeleton creatures to have a hefty exoskeleton construction, hence the animals are smaller in size. Proteins, carbohydrates, and minerals make up the exoskeleton’s outer layer. The exoskeleton is made up of chitin, a material generated by epidermal cells, and protein.
The arthropod cuticle and the shell are the two forms of exoskeleton animals that fall within this category.
Difference Between Endoskeleton and Exoskeleton
- The endoskeleton is an internal skeleton, while the exoskeleton is an exterior skeleton that is positioned outside of the organism’s body.
- Vertebrates have an endoskeleton, while arthropods have an exoskeleton.
- Calcium and phosphorus are the primary building blocks of the endoskeleton. Several proteins, carbohydrates, and minerals make up the outer layer of the exoskeleton.
- Endocrine cells produce the endoskeleton and ectoderm are responsible for creating the exoskeleton, respectively.
- The endoskeleton allows the body to move freely, but the exoskeleton restricts the body’s motions at particular periods.
- Unlike the exoskeleton, which does not expand with the body, the endoskeleton grows with the body from infancy to maturity.
- As a result, most creatures have a smaller exoskeleton than an endoskeleton, which is why they are smaller in size.
- Bones in the endoskeleton do not encourage or permit blood supply, while those in the exoskeleton do not.
Conclusion
Skeletons are an essential part of all living things. When it comes to skeletons, there are two main types: the endoskeleton and the exoskeleton. While vertebrates have an endoskeleton and arthropods have an exoskeleton, the two groups are quite different. Location, organisms found in, development from, a material formed of, flexibility, growth, support, and blood supply are just a few of the factors that help to distinguish between the endoskeleton and the exoskeleton.
The endoskeleton is a network of connective tissue that spans the interior of the body and acts as a structural support system. Flexible mobility is also aided by it. When the body needs it, it gets the nutrition it needs from it. A body’s defenses are provided by an exoskeleton, which surrounds and protects the human body from harm. The exoskeleton does not expand with the body, hence the body must, on a regular basis, shed it.
