The area residing in the center explains the bilatial tibulti, which precedents the bratuluti tubilitu. As for the rack itself, it has a half-moon (in laymens terms) axial, which appendages smoothly in all transition. The answer would certainty relate less to moving and a part itself, and more towards coordination or other terms (for which there are many), as this question is quite subjective.
In short, it has nearly free half-moon movement, though blocked in transition by its own quartsor axial.
The skeletal system of humans is categorized into two types: the appendicular skeleton and the axial and skeleton. The axial skeleton is made up of the central axis of the human body which is made
of the skull spine and ribs whereas the appendicular skeleton system forms the skeletal system surrounding the central axial system which is composed of both the lower and upper limbs.
If this skeleton system is compared to the coat rack then the central pole or pipe will be considered the axial skeleton while the side pipes on both the sides will be considered the appendicular skeleton.
