Did you know that humans have an endoskeleton?

Really? I thought all skeletons were external like in insects.

Nope, ours is internal, which helps support our body.

That's pretty cool! It makes sense for a flexible body like ours.

Root Explanation

Endoskeleton → It is formed from "endo-" (from Greek "endon", meaning within) and "skeleton" (from Greek "skeletos", meaning dried body or skeleton). The word "endoskeleton" refers to a skeleton that is located within the body, as opposed to an exoskeleton which is on the outside.

Memory Tip

Think of 'endo-' meaning 'within' and 'skeleton' referring to the structure of a body. This helps you remember that an endoskeleton is a skeleton that is found inside the body.
