Depends on how you define "fails".
If a body has no skeletal system, it's pretty much just a bag of jelly because everything else in the body is soft and holds no firm shape.
All the sytems will fail and you will die
the skeletal system is bones. They dont fail, they break. Of course, if a leg, foot, or thigh bone breaks, you WILL fall and roll in pain. If the skull breaks, you may get a concussion.
Skeletal muscles .
Cartilage is from the skeletal system.
The muscular and skeletal systems coordinate to produce movement. The skeletal system provides levers against which the contractions of the muscular system can act.
