endoskeletal
Having inner framework
Endoskeletal describes having or relating to an internal skeleton, as opposed to an exoskeleton worn on the outside like a shell or carapace.
Humans and other vertebrates are endoskeletal creatures, with bones inside their bodies providing structure and protection.
The term appears in biology and also in robotics and engineering, where an endoskeletal prosthetic limb has its structural components inside rather than as an outer frame.
