NCERT Solutions for Class 6 Science Chapter 5 Body Movements

Body movements class 6 questions and answers are a fantastic way for students to learn the secrets of how people and animals move from one place to another. Have you ever wondered how you can bend your elbow, turn your head, or how a tiny earthworm can crawl through the soil without any legs? In this chapter, we look at the amazing system of bones and muscles hidden inside us. We also find out how different creatures in nature have unique ways of traveling. These solutions cover all the tasks, activities, and questions found in your science book to make learning fun and easy.

Learning About Body Movements Class 6 Questions and Answers

When you start this chapter, you will see that your body is like a highly advanced machine with many moving parts. The hard, strong parts inside you that you can feel under your skin are called bones. All your bones together join to make a framework called the Skeleton. The skeleton is like the wooden frame of a house; it gives your body its shape and protects the soft organs inside, like your brain and heart.

Students looking for body movements class 6 questions and answers NCERT will find that we can move because of Joints. Joints are the special places where two or more bones meet. If our body was just one long bone, we would be as stiff as a piece of wood and couldn't even sit down!

Finding the body movements class 6 questions and answers helps you see how different types of joints allow different kinds of moves:

• Ball and Socket Joint: This is where the round end of one bone fits into the cup-like hole of another. It lets you move your limb in all directions, like a joystick. You have these in your shoulder and hip.

• Hinge Joint: This joint works just like the hinge on a bedroom door. It only lets you move back and forth. Your elbows and knees are great examples of this.

• Pivotal Joint: This is a joint that lets you turn and rotate. Your neck has a pivotal joint that allows you to turn your head left, right, up, and down.

• Fixed Joint: Some joints are special because they do not move at all. These are "fixed." For example, while you can move your lower jaw to eat and talk, your upper jaw is stuck to your skull and does not move.

Body Movements Class 6 Questions and Answers

The NCERT Solutions for Class 6 Science Chapter 8 feature a variety of questions, including fill-in-the-blanks, match the following, true or false, and descriptive answer questions. All responses are crafted by subject experts from PhysicsWallah, supporting students in their CBSE Class 6 exam preparation. 1. Fill in the blanks. (a) Joints of the bones help in the ——————— of the body. (b) A combination of bones and cartilages forms the _______ of the body. (c) The bones at the elbow are joined by a ______________________ joint. (d) The contraction of the _____________ pulls the bones during movement. Solution: (a) Joints of the bones help in the movement of the body. (b) A combination of bones and cartilages forms the skeleton of the body. (c) The bones at the elbow are joined by a hinge joint. (d) The contraction of the muscles pulls the bones during movement.

2. Indicate true (T) and false (F) among the following sentences. (a) The movement and locomotion of all animals are exactly the same. ( ) (b) The cartilages are harder than bones. ( ) (c) The finger bones do not have joints. ( ) (d) The forearm has two bones. ( ) (e) Cockroaches have an outer skeleton. ( ) Solution: a ) False b ) False c ) False d ) True e ) True 3. Match the items in Column I with one or more items of Column II. Solution:

Solution:

4. Answer the following. (a) What is a ball and socket joint? (b) Which of the skull bones are movable? (c) Why can our elbows not move backwards? Solution: a) The rounded end of one bone fits into the cavity (hollow space) of the other bone. Such a joint allows movements in all directions, which is called a ball and socket joint. b) Lower jaw c) Our elbow cannot move backwards because it has hinge joints which only allow back-and forth-movement.

The Official Science Answer Guide Explained

To get the body movements class 6 questions and answers, you must understand the "engine" that moves the bones: Muscles. Bones are strong, but they cannot move by themselves. They need muscles to pull them.

Muscles are amazing because they always work in pairs as a team. When you want to bend your arm, the muscle on the front (your biceps) gets short, fat, and tight. This is called contraction. When a muscle contracts, it pulls the bone. While the front muscle pulls, the muscle on the back (your triceps) relaxes. The most important rule to remember is that a muscle can only pull a bone; it can never push it. To move the bone back to its original spot, the second muscle must contract while the first one rests.

Think of it like a game of tug-of-war. The body movements class 6 questions and answers show you that not all animals use bones to move. Some, like the earthworm, have no bones at all! They use only muscles to make their body long and then short to pull themselves forward. Snails move very slowly using a large, flat muscle called a foot, which secretes a slippery trail to help it glide. Using a good study guide is the secret to doing well in class and understanding these natural wonders.

Class 6 Body Movements Question and Answer Examples 

Let’s look at some simple body movements class 6 questions and answers examples. These are common questions that will help you understand the main ideas of the chapter quickly.

• Question 1: Which part of the body protects our heart and lungs?

• Answer: The Rib Cage. It is a strong box made of 12 pairs of curved bones in our chest area.

• Question 2: Which bone in our head is the only one that can move?

• Answer: The lower jaw is the only movable bone in the head. This allows us to chew our food and speak to our friends.

• Question 3: Do cockroaches have an internal skeleton like humans?

• Answer: No. Cockroaches have a hard shell on the outside of their body called an outer skeleton or exoskeleton. It protects them and helps them walk using their three pairs of legs.

• Question 4: What is the backbone made of?

• Answer: It is made of 33 small, ring-like bones called vertebrae. Because there are many small bones instead of one long one, we are able to bend forward and touch our toes!

Doing Your Best with NCERT Solutions

Working with body movements class 6 questions and answers is the best way to do well in your school work. You will learn about a topic called the "Gait of Animals," which is just a scientific way of talking about the different styles of walking and moving.

You can find the answers by looking closely at these specific body parts:

• Cartilage: Not everything in our skeleton is as hard as a bone. Some parts are softer and can be bent. This is called cartilage. You can feel it in the upper part of your ear or at the very tip of your nose. Cartilage is also found between joints to help them move smoothly without rubbing.

• Pelvic Bones: These are the large bones that enclose the part of your body below your stomach. These are the bones you sit on!

• Forearm: Did you know that the part of your arm between the elbow and the wrist actually has two bones? This allows you to twist your wrist to turn a doorknob.

Common mistakes to avoid include thinking that our finger bones are just one solid piece. Remember, every time you bend your finger, you are using a tiny joint! If your fingers didn't have joints, you wouldn't be able to hold a pencil or tie your shoelaces.

The Secret of Animal Movement

One of the most exciting parts of body movements class 6 questions and answers NCERT is learning how animals move without the same skeleton we have.

How Fish Swim

Fish have a streamlined body. This means their head and tail are smaller than the middle portion of their body. This shape allows water to flow over them easily. Fish move by making a curve with their body on one side and a curve on the other side very quickly. This creates a "jerk" that pushes the fish forward.

How Birds Fly

Birds are built for the sky. Their bones are hollow and light, which makes it easy for them to stay in the air. Their breastbones are very strong and hold massive flight muscles that move their wings up and down.

How Snakes Slither

Snakes have a very long backbone and many thin muscles. They move by forming many loops. Each loop of the snake gives it a forward push by pressing against the ground. This is why snakes move in a curvy or "S" shape and can go very fast!
