Endoskeleton And Exoskeleton with tabular form

The endoskeleton and exoskeleton are two of the body parts of some living organisms. These two parts of the body of organisms are integrated into a complicated network of various organs . Endoskeleton And Exoskeleton with tabular form

In this article I discuss the main differences between an edoskeleton and an exoskeleton. So if you are interested, keep reading. Let us begin!

The main difference between these two types of skeletons is that the exoskeleton is present outside the body of the animal. Instead the endoskeleton is located within the body.

What is an endoskeleton? Endoskeleton And Exoskeleton with tabular form

The hard part that is the internal support of the structure is called the endoskeleton. It develops from the endoderm and is called a living structure. Some examples of endoskeleton are cartilage, bone, etc.

Examples of animals with endoskeletons 

  • Fishes
  • Birds
  • Mammals
  • Reptiles

What is an exoskeleton? Endoskeleton And Exoskeleton with tabular form

The hard part outside the body that protects soft tissues and muscles is called the exoskeleton. It develops from the ectoderm and is primarily called a non-living structure. Some examples of exoskeleton are hair, feathers, scales, horns, etc.

The endoskeleton is made up of three structures

  • Cuticle
  • The hypodermis
  • The basement membrane

Examples of animals with exoskeletons

  • Crab
  • Centipedes
  • Bee

Differences between endoskeleton and exoskeleton

Endoskeleton Exoskeleton
Definition Refers to the internal skeleton. Refers to the external skeleton.
Is found in Vertebrates Arthropods
Structure Alive Lifeless
It takes place in Endoderm Ectoderm
Made of Phosphorus and calcium Calcified shells, scales, cuticle.
Location Inside the body Outside
It grows with the body Yes Not
Flexibility More flexible Less flexible
