Which of the following parts of our body help us in movement? (i) Bones (ii) Skin (iii) Muscles (iv) Organs choose the correct answer from the option below. (a) (i) and (iii) (b) (ii) and (iv) (c) (i) and (iv) (ii) and (iii)
: (i) and (iii) Bones form the structural framework of body called skeleton. The skeleton along with muscles helps our body parts to move. Bones are hard and cannot bend on their own. The joints help the body in moving. Muscles are like elastic bands which are attached to the bones by means of tough connecting bands called tendons. Muscles help in movement of bone through pull/contraction. Bones are wrapped up by muscles.
