Question 1.
\nWhat is movement?
\nAnswer:
\nThe displacement of a body or its parts from its original position is called movement.<\/p>\n

Question 2.
\nWhat is locomotion?

6th Class Science 12th Lesson Movement and Locomotion 4 Mark Important Questions and Answers<\/h3>\n

Question 1.
\nHow do you observe the shoulder muscles?
\nAnswer:
\nMake a fist with one hand, bend your arm at the elbow and touch your shoulder with the fist.
\n\"AP
\nAlso, touch your upper arm with the other hand, you feel a swollen region inside your upper arm. This is muscle.
\nThe muscle bulges due to contraction.
\nWhen the muscle is contracted it becomes shorter, stiffer, and thicker.<\/p>\n

\"AP<\/p>\n

Question 2.
\nIs it possible to move your parts without moving muscles? Why?
\nAnswer:
\nIt is not possible to move the body parts without moving muscles.
\nMuscles are fleshy structures that cause movement.
\nThese are attached to one another and perform contraction and relaxation.
\nBy these contractions, bones are pulled in that direction that makes the movement.<\/p>\n

Question 3.
\nHow do Muscles work?
\nAnswer:<\/p>\n

    \n
  1. Muscles work in pairs.
    \n\"AP<\/li>\n
  2. When one of them contracts, the bone is pulled in that direction and the other muscle of the pair relaxes.<\/li>\n
  3. To move the bone in the opposite direction, the relaxed muscle contracts and the first one relaxes.<\/li>\n
  4. Thus two muscles have to work together to move a bone.<\/li>\n<\/ol>\n

    Question 4.
    \nWhat is Tendon? What is its role in our body?
    \nAnswer:
    \nSome muscles have round, white, and rope-like fibers at their ends that connect them to the bone.
    \nThese fibrous structures are called Tendons.
    \n\"AP
    \nYou can feel the tendons in several parts of your body like; above the elbow, beneath the knee, near the ankle.
    \nThey have a key role in body movements to pull the bones.
    \nThese also help muscles to attach to the bones.<\/p>\n

    Question 5.
    \nWhat is Skeleton System? What is its importance?
    \nAnswer:<\/p>\n

      \n
    1. The different bones of different parts of the body combine together to form a single structure or system. This structure is called the skeleton.<\/li>\n
    2. The skeletal system provides base and shape to our body.<\/li>\n
    3. It provides protection to internal organs.<\/li>\n
    4. It also help in blood formation.<\/li>\n<\/ol>\n

      \"AP<\/p>\n

      Question 6.
      \nWhat is a ligament? What is its use?
      \nAnswer:
      \nTwo bones are joined together in a special way by fibers. These fibers are called ligaments These helps in bones connection and body movements.
      \n\"AP<\/p>\n

      Question 7.
      \nHow we are without a skeleton.
      \nAnswer:<\/p>\n

        \n
      1. It’s funny to imagine our body without a skeleton.<\/li>\n
      2. Without a skeleton, muscles don\u2019t have support.<\/li>\n
      3. So the body does not have a shape.<\/li>\n
      4. The body becomes a fate round ball.<\/li>\n<\/ol>\n

        Question 8.
        \nHow do you observe the lower jaw bone?
        \nAnswer:
        \nAsk your friend to open his mouth and move his lower jaw up and down as well as sideways.
        \nObserve his face carefully.
        \nThis is the place where the lower jaw bone is joined to the skull.
        \nPress your finger on both sides of your face and spot where you have these joints. This lower jaw is the only movable joint of another skull.<\/p>\n

        Question 9.
