Body Movements Class 6 science chapter 8 Important Questions

Science is an area of study that deals with the natural world. Body movement is the eighth chapter in the Class 6 Science syllabus. Movement is the body’s change of place or position from one position to another. Muscles are tissues that can contract and help in the movement of other body parts. By moving, you can strengthen your muscles, improving stability, balance, and coordination. It also allows blood to flow. Movements are brought about by the joint efforts of the skeletal and muscular systems.

Question 2. Which of the following joints is immovable?

(a) Shoulder and arm

(b) Knee and joint

(c) Upper jaw and skull

(d) Lower jaw and upper jaw

Answer 2: The joints in the upper jaw and skull are fixed. There is no mobility between the bones involved in this type of joint. These joints are hence fixed and immobile.

Question 3. Name various parts of the skeletal system.

Answer 3: The skeletal system can be divided into the following main parts:

  • Skull
  • Limb bones
  • Backbone
  • Shoulder bones
  • Chest bones
  • Hip bones.

Question 4. Keeping your arm straight, move it forwards and backwards, up and down. Can the arm move freely without any restrictions in all directions?

Answer 4: Yes, the arm can move freely in all directions, i.e. forward, backward, down and up.

Question 5. Do all animals have bones?

Answer 5: No, not all creatures have bones. The only creatures with bones are those with backbones. Sharks’ skeletons are the only ones fully formed of cartilage among animals with backbones. The bodies of leeches, worms, and jellyfish are not supported by solid structures.

Question 6. What is bone marrow? Give its main function.

Answer 6: Bone marrow is a spongy substance found in the centre of the bones. Its main function is to produce new blood cells to replace damaged and worn-out ones.

Question 7. Which organisms do not have muscles or a skeleton for movement?

(a) Dog

(b) Snail

(c) Earthworm

(d) Human being

Answer 7: None

Explanation: The skeleton is absent from earthworms. There are two sets of muscles in it, one of which makes it long and thin and the other of which makes it fat. These muscles’ contractions and relaxations facilitate movement. Exoskeletons and muscles are present in snails. Dogs and humans both have muscles and an endoskeleton.

Question 8. What would have happened if our backbone had been made of one single bone?

Answer 8: If our backbone had only one bone, we would not  be able to bend and twist our backbone.  .

Question 9. How many types of joints are there? Explain each of them.

Answer 9: The main types of joints in the human are:

  • Hinge joint
  • Ball and socket joint
  • Pivot joint
  • Fixed joint

(i) Hinge joint: Hinge joints allow bones to move in only one direction, i.e. back and forth.

(ii) Ball and socket joint: A “ball”-shaped bone end that fits into a “socket” (hollow space) in another bone makes up the ball and socket joint. Such joints, like the hip and shoulder joints, permit movement in all directions.

(iii) Pivot joint: A cylindrical bone rotates within a ring-shaped bone in a pivot joint. The pivot joint permits movement in both directions, including right and left, for example, at the neck joint.

(iv) Fixed joint: In certain joints, the bones are held together so firmly that they are completely immobile.

Question 10. Boojho hurt his ankle after falling off a tree. The doctor found that the ankle was fractured after the examination. How was it detected?

Answer 10: A doctor must have examined the affected area for oedema and obtained an ankle X-ray. The forms of the bones in our body are visible in X-ray scans. The doctor may have confirmed a fracture in the ankle by glancing at the x-ray.

Question 11. List the organs that are protected by the rib cage.

Answer 11: The organs that are protected by the rib cage are

  • Heart and
  • Lungs

Question 12. Why do animals move from one position to another?

Question 21. Bones are hard structures and cannot be bent. However, we can still bend our elbows, knees, etc. How is this possible?

Answer 21: The existence of several types of joints between the bones allows us to bend various bodily parts, including the elbow, knee, back, etc. The hinge joint connects two or more bones, which make up the elbow and knee, rather than just one bone. We can bend our elbows and knees with the help of these muscles and this joint.

Question 22. What is the name of the small bone which makes up the backbone?

Answer 22: Vertebrae is the name of a small bone which makes up the backbone.

Question 23. What is cartilage?

Answer 23: Cartilage is a soft, elastic, and flexible connective tissue. It prevents the bones from rubbing against one another.

(a) shell

(b) bone

(c) muscular foot

(d) whole body.

Answer 24: (C)The snail’s strong muscular foot extends outside during locomotion and is attached to the ground. It creates a sequence of waves that the snail can use to propel itself forward. A unique gland in a snail’s foot produces a slimy mucus that creates a slick surface that helps the snail walk more easily.

Question 25. Name the longest bone in our body.

Answer 25: The femur is the longest bone in our body.

Question 26. What is a skeleton? State its functions.

Answer 26: The skeleton is the framework of bones and cartilage that supports and protects the body’s soft tissues and internal organs.

Functions of the skeleton:

  • The skeletal system provides shape to the body.
  • It works as a support structure for your body.
  • It facilitates movement.
  • It produces blood cells.
  • It protects organs.
  • It stores minerals and fats.

Question 27. List the names of three animals that have streamlined bodies.

Answer 27:

  • Birds
  • Fishes
  • Snakes

Question 28. What is a muscle? Explain how it helps in movement.

Answer 28: Muscles are soft tissues. Many stretchy fibres make up your muscles. Different types of muscles have different functions. . Muscles are attached to the bones through a long fibre called a tendon. There are more than 600 muscles in our body.

Muscles always function in pairs. In a pair of muscles, when one contracts, the other muscle relaxes. A muscle can only return to its initial position after the other muscle in the pair contracts.
