Anatomical system consisting of multiple elements and tissues that provides physical support.[TAO], Anatomical system that is a multi-element, multi-tissue anatomical cluster that consists of the skeleton and the articular system.[VSAO], System that provides physical support to the organism.[AAO]

GO defines skeletal system very generically: The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton) GO:0001501; however, all annotations are to vertebrates
