Endoskeleton
An endoskeleton is the body’s internal skeletal framework that supports and shields its internal organs.
It is made up of joints that join bones, cartilage, and ligaments to allow for movement.
Humans are among the vertebrates that have endoskeletons, along with some other invertebrates like echinoderms and cephalopods.
Characteristics of Endoskeleton:
- Made of cartilage or bones.
- The skeletal system inside the body.
- Organs are supported and shielded by this.
- Enables flexibility and movement.
- Grows and changes alongside the animal.
Advantages of Endoskeleton:
- Allows for more flexibility and range of motion.
- Makes it possible for larger body sizes to develop.
- Greater weight capacity than an exoskeleton.
- Can regenerate and repair harmed tissues and bones.
Disadvantages of Endoskeleton:
- Energy is needed to maintain and repair.
- Vulnerable to illness and injury.
- Can in some circumstances limit growth and mobility.
Difference Between Endoskeleton And Exoskeleton
Exoskeletons and endoskeletons are two different categories of support systems that can be found in the animal kingdom. An exoskeleton is an external hard covering that encases the body and serves as support and protection, whereas an endoskeleton is an internal framework made of bones or cartilage that offers support, protection, and anchorage for muscles. Invertebrates like echinoderms (like starfish) and cephalopods as well as vertebrates like humans have endoskeletons (e.g., squid).
The majority of arthropods, such as insects, crustaceans, and arachnids, as well as some mollusks, like snails and clams, on the other hand, have exoskeletons.
Exoskeletons and endoskeletons both serve as structural supports, but they are distinct in terms of their location, make-up, and developmental origins.
Understanding these variations can help us better understand the special adaptations and skills that these various skeletal system types in animals have developed over time.
