Endoskeleton

Real World Example

Imagine trying to build a sturdy sandcastle on the beach without any support inside to keep it from collapsing. Just like the hidden structure of sticks or straws you might use inside the castle to give it shape and strength, an endoskeleton provides an internal framework for the body. The endoskeleton, made of bone and/or cartilage, acts like those internal supports, ensuring that the body maintains its form and can withstand external pressures, much like the hidden struts keep your sandcastle upright against the wind and waves.
