ANATOMY

Detailed explanation-1: -An exoskeleton (from Greek éxō “outer” and skeletós “skeleton") is an external skeleton that supports and protects an animal’s body, in contrast to an internal skeleton (endoskeleton) in for example, a human. In usage, some of the larger kinds of exoskeletons are known as “shells ".

Detailed explanation-2: -A skeletal system is necessary to support the body, protect internal organs, and allow for the movement of an organism. There are three different skeleton designs that fulfill these functions: hydrostatic skeleton, exoskeleton, and endoskeleton.

Detailed explanation-3: -The skeletal system is your body’s central framework. It consists of bones and connective tissue, including cartilage, tendons, and ligaments. It’s also called the musculoskeletal system.

Detailed explanation-4: -The framework of the body, consisting of bones and other connective tissues, protects and supports the body tissues and internal organs. The human skeleton contains 206 bones, six of which are the tiny bones of the middle ear (three in each ear) that function in hearing.

Detailed explanation-5: -Vertebrates are animals that have backbones and an endoskeleton (skeleton inside their bodies). In contrast, invertebrates are animals that do not have backbones. Invertebrates can have a skeleton outside their bodies called an exoskeleton, while some invertebrates have no skeleton at all!
