internal
Endoskeleton is the internal skeleton, which is what most people refer to when they just say skeleton. The exoskeleton, on the other hand, is an external skeleton which has protective features, eg crustaceans hard shell.

A human skeleton is internal and made up of bones, providing structure and support to the body. Insects have an exoskeleton, which is a hard outer shell that covers their body for support and protection. Insects molt their exoskeleton to grow, while humans do not.
An endoskeleton is an internal skeleton found in vertebrates, like humans, composed of bones and cartilage. Conversely, a human skeleton specifically refers to the endoskeleton of the human body. The main difference would be in the specific structures composing each skeleton, but both serve to support and protect the body.
