Solution

Part (a): Unscrambled words:
(i) neosb - bones
(ii) tnemevom - movement
(iii) iontcaronct - contraction
(iv) lsecsum - muscles
(v) arctigeal - cartilage
(vi) epahs - shape
(vii) sangro inerlan - internal organs
(viii) laxaeriont - relaxation

Part (b): Framework of the body:
The main structure of the body system in controlled by all types of skeletal tissues.
It helps maintain the framework of the body and protects the visceral organs.
Bones are directly associated with muscles forming the musculoskeletal system.
Final answer: Bones and cartilage form the skeleton of the human body. They provide the framework, give shape to the body and help in movement. They protect the internal organs. The bones are moved by alternate contraction and relaxation of two sets of muscles attached to them.
