Endoskeleton and Exoskeleton are the parts of the body of living organisms which possess a body with a complicated network of various organs.
The hard part which is the internal support of the structure is called an endoskeleton. It is developed from endoderm and is called a living structure. Some examples of endoskeleton are cartilage, bone, etc. The hard part present outside the body which protects the soft tissues and muscles is called the exoskeleton. It is developed from ectoderm and is mostly called a non-living structure. Some examples of the exoskeleton are hair, feather, scales, horns, etc.
