Endoskeleton and Exoskeleton

Endoskeleton and Exoskeleton are two types of skeletons. They are both composed of bones and cartilage, but they differ in their position on the body and their function. Endoskeleton is an internal, or inside skeleton. The Endoskeleton provides support for the body and encloses most organs, protecting them from harm. You can usually find the Endoskeleton within a person’s skull, ribs or spine as well as within muscles such as those found in your arms and legs. Exoskeleton is an external skeleton that supports a person’s body from outside that person’s own skin (an exo means from outside).

What is Endoskeleton?

Endoskeleton is a type of internal skeleton that supports the body from within the body. There are three general types of Endoskeletons: Axial (head, spinal column, ribs), Appendicular (joints, muscles and limbs), and Muscular.

Endoskeleton: Function

The endoskeleton serves many functions in the human body including providing the framework for the body and protecting certain organs like the heart and lungs; acting as a support structure for muscle; helps to distribute fluids throughout the body; protects certain organs such as heart and lungs, which can’t be safely contained inside of a person’s rib cage; helps to keep bones strong so they can support the weight.

What is Exoskeleton?

The exoskeleton is an outside skeleton that helps protect a person’s body from the outside world. There are three general types of exoskeletons: Epidermal, Integumentary, and Lamellar. All exoskeletons are external skeletons that provide protection for a person’s body from the outside world.

Exoskeleton: Function

The main functions of the exoskeleton include providing structural support for some protective functions as well as enabling some movements in many joints such as a bird’s wing or walking on two feet. Some other vital functions are:

• Serving to protect tissue and organs.
• Supporting weight on the surface (also called weight bearing)
• Providing an extra surface on which heat can dissipate (or insulate)
• Providing a unique shape and texture

Similarities and Differences 

There are several similarities between the two skeletons. Both skeletons are made up of bones that support the body from inside, with supporting cartilage in time between them. Bones are attached to one another by strong ligaments called fibres that provide strength for joints. They both house some internal organs such as the heart and lungs too. Exoskeletons can also help with movements in some joints, as well as provide some protection from the environment.

Endoskeleton and Exoskeleton: Difference

1. Endoskeleton is an internal skeleton that provides support and protection to the body’s organs while Exoskeleton is an external skeleton which provides protection to the body from outside.
2. Endoskeleton is found within the human body while Exoskeleton works external to the human body.
3. In the case of the endoskeleton, it contains a few small bones found in joints while in Exoskeleton, it has more large bones which play a role in limbs (arms and legs).
4. The endoskeleton consists of two main parts, one is the central nervous system (CNS) and the other is the peripheral nervous system (PNS). The exoskeleton consists of four main parts, they are epidermis, dermis, hypodermis and subcutaneous tissue.
5. The endoskeleton helps in the movement of skeletal muscles while Exoskeletons help in the movement of muscle and bones.
6. Endoskeletons provide the framework for the body while exoskeletons work as support structures for muscles.
7. The exoskeleton helps in the movement of skeletal muscles and bones while the endoskeleton helps in providing the framework for the body.
8. Endoskeletons help in the distribution of fluids throughout the body while exoskeletons help in bodily protection.
9. Endoskeletons keep bones strong and prevent them from breaking while Exo skeletons protect a person’s body from any harm.
10. The main function of an endoskeleton is to protect and provide support to vital organs or parts of a person’s body, but there are many functions of exoskeletons other than protecting and providing support to vital organs or parts of a human body.

Conclusion

The body contains both the endoskeleton and exoskeletal system. Both are needed to serve different purposes, which is why there is no difference between the two, yet they differ in structure, functions and purpose. Endoskeleton is an internal skeleton of a human or any animal while Exoskeleton is external in nature. In the case of endo, it contains a few small bones found in joints while in Exo, it has more large bones which play a role in limbs (arms and legs). The endoskeleton consists of two main parts, one is the central nervous system (CNS) and the other is the peripheral nervous system (PNS).
