Question 4. Fill In the table given below showing different types of movement in our body.

Answer:

Question 5. Why is it that we can move a few parts of our body easily in various directions and some only in one direction? Why are we unable to move some parts at
Answer: We can move a few parts ofour body easily in various directions and some only in one direction. Some parts are fixed, i.e. they do not move at all. This is because the movement depends upon the type of joint that joins two or more bones together.

For example, the body parts having ball and socket joints move in all directions, while the body parts having hinge joints move only in one direction. The body parts having fixed joints are unable to move at all.

Question 6. How do we bend our elbows?
Answer: The elbow is not one long bone from the upper arm to our wrist. It consists of different bones joined together at the elbow. The joint present at the elbow is the hinge joint that helps in bending

Question 7. How many bones does the middle finger have?
Answer: The middle finger has three bones.

Question 8. Are muscles and bones always required for mo Pages
Answer: Yes, muscles and bones are always required for movement.

Question 9. Do all animals have bones?
Answer: No, all animals do not have bones. For example, earthworms.

Question 10. How does an earthworm fix parts of its body to the ground?
Answer: Earthworms possess a large number of tiny projections called bristles. These bristles are connected with muscles. They help to get a grip on the soil and thereby, help the earthworm in fixing parts of its body to the ground.

Question 11. Is the movement of a snail slow or fast as compared to an earthworm?
Answer: The movement snail is slow as compared to an earthworm.

Question 12. Why do different animals have the body parts that they do have and how do these body parts help animals to move the way they do?
Answer: Use of the differences in the way of their movement. For example, a snail has a thick muscular foot for movement Cockroach has three pairs of legs that help in walking.

Question 13. What are the differences in body parts between different animals used for movement? 
Answer: Animals of different kinds of body structures move in different ways using different body parts such as legs, wings, fins, tails, etc. These help them to walk, jump, fly, swim, run, etc.

Question 14. Why are there two legs for humans and four for cows and buffaloes?
Answer: Technically, humans do have four legs however when we evolved, the muscles in our legs grew stronger and longer, allowing us to stand upright. However, cows did not evolve with time and they still need four legs to balance themselves and around.

Question 15. Why is the bending of our legs different from that of our arms?
Answer: The bending ofour legs is different from that ofour arms because of the differences in their position and role in our body. Although they both are hinge joints, they bend in opposite directions.

Question 16. Distinguish between the following

1. Movable joint and fixed joint
2. Ball and socket joint and hinge joint

Answer: Differences between movable joints and fixed joints are as follows

Differences between Ball and socket joint and hinge joint are as follows-

Question 17. Draw a diagram to show the Joint In the hand and answer the following questions.

1. Can you bend your finger at every joint?
2. How many bones are there in a human skull?
3. Is your wrist flexible?
4. What would happen if your hand had only one bone?

Answer:

• We can bend our fingers at every joint.
• The human skull has 22 bones
• Yes, our wrist is flexible.
• If our hand had only one bone, then we would not be able to bend our fingers and other parts of our hand

Question 18. How is the skeleton of a bird well-suited for flying?
Answer: The skeleton of a bird is well-suited for flying because

• Bones are hollow and light in weight.
• Bones of hindlimbs are used for walking and perching.
• The bones of the forelimbs are modified as wings.
• Shoulder bones are strong and helpful in flying.
• Breast bones hold flight muscles and are used to move the wings up and down for flying.

Question 19. In the figure given below, there are two snakes of the same size, slithering on sand. Can you identify which of them would move faster and why?

Answer:

A snake forms loops in its body while slithering. Each loop of the snake gives it a forward push by pressing against the ground.

The snake with a larger number of loops will move much faster than the snake with a lesser number of loops. Thus, snake A will move faster than snake B as we can see that loops in snake A are more than in snake B.

4. Snail — Creeping
5. Snake — Slithering
6. Fish — Swimming
7. Human being — Walking and running
8. Cockroach — Walking and flying

Question 2. Which type of movement would have been possible if

1. Our elbow had a fixed Joint.
2. We were to have a ball and socket joint between our neck and head

Answer: If our elbow had a fixed joint, we would not be able to bend or fold our arms. A fixed joint does not allow any movement.

If we were to have a ball and socket joint between our neck and head, we would be able to rotate our head 360°. A ball and socket joint allows movement in all directions.

Question 3. Bones are hard structures and cannot be bent, but we can still bend our elbows, knees, etc. How is this possible?
Answer: The elbow and knee are not made up of a single bone rather they are made up of two or more bones that are joined to each other at a joint, i.e. hinge joint. This joint along with the muscles helps us to bend the elbow and knee.

Question 4. Study the classification chart given below

What are A and B? Why?

Answer: A is the movable joint, which is further classified into

• Ball and socket joint-e.g. hip joint and shoulder joint.
• Pivotal joint – example between neck joint and head joint.
• Hinge joint – Example elbow joint and knee joint.
• B is the immovable or fixed joint. It is located within the skull. The upper jaw is fixed to the skull bones with the help of fixed joints.
