Short Answer Questions:                                                  3 Marks

3. Define joints. Explain its importance.

Ans: The regions of the body where two bones meet and connect are known as joints. Joints are necessary for the movement of body parts. Bones are strong, rigid support that provide the body with a framework and structure. The action of muscles allows the bones to move through joints. Different types of joints in the body allow for various motions.

4. List the various joints in the human body with examples.

Ans: The following are the most common types of joints found in the human body: 

  1. Ball and socket joint: found in the shoulder and hip joint.

  2. Pivotal Joint: This joint connects the head to the shoulder and is located in the neck.

  3. Hinge Joint: Elbows and knees have hinge joints.

  4. Fixed Joints: These are located in the skull.

  5. Gliding Joints: This is found in joints of the wrist.

  6. Saddle Joints: Present in thumb.

5. Explain how muscles work to cause movements in bones.

Ans: Muscles are soft contractile structures that contract to move the body. Muscles shorten and stiffen as they contract. The bone is pulled and moves as a result of this movement. Muscles function in pairs. When one of the muscles contracts the other unconsciously relaxes. The bone is pulled in one direction by the contracted muscle. The other muscle in the pair contracts as the first relaxes to return the bone to its previous position. This causes the bone to migrate in the opposite direction because muscles can only pull and not push, this pair wise action is critical.

6. Explain how a fish body is designed to swim in water.

Ans: A fish is an aquatic creature. It has a sleek appearance. The head and tails are smaller than the main portion of the fish in this shape. This allows the water to flow freely around the fish. The muscles in a fish's body are also quite powerful, allowing them to swim easily. The muscles in the front half of the body curve to one side, while the muscles in the back section of the body curve to the opposite side. The body jerks forward as a result of this. The tail and fin muscles help the fish to maintain its balance and direction also.

7. Why do snakes not move forward in a straight line?

Ans: The snake's body is twisted into a tangle of loops. The snake's body is made up of several muscles that are linked to one another and to the skeleton's bones. Each of the snake's loops is moved by these muscles. As a result, each snake loop pushes forward by pressing on the ground. As the snake body is made up of numerous individual loops that push and move forward, it does not move in a straight line, even though it moves incredibly swiftly.

8. What is meant by skeleton? What is the importance of skeletal structure? List the important parts of the skeleton.

Ans: The skeleton is the body's basic structural structure, which is made up of bones.

The importance of the skeletal structure is as follows:

  1. It provides the body's basic structural framework.

  2. It aids in the support of various body components.

  3. It shields the internal organs from harm.

  4. It aids in motility and mobility.

The important parts of the skeleton are as follows:

  1. Skull: The skull is a collection of bones which encase the brain and give form to the head and face.

  2. Vertebral Column: This is the backbone that supports the body's posture and shape. The spinal cord is also contained inside it.

  3. Rib cage: The ribs and the sternum make up the rib cage. Protects the internal organs of the chest cavity, such as the heart and lungs. 

  4. Shoulder/pectoral girdle: This consists of the shoulder blade, as well as a ball and socket joint for the arm's attachment.

  5. Hip/pelvic girdle: The ball and socket joint that connects the leg to the pelvis. It also houses all of the hip bones.

  6. Limbs: Arms and legs are made up of bones.

9. Compare ball and socket joints with pivot joints.

Ans: Difference between ball and socket joints and pivot joints are as follows:

Ball & Socket Joints

Pivot Joint

  • It is like a ball in a socket, it is rounded end of one bone fits into the hollow chamber of the other.

  • A cylindrical bone rotates within another bone's circle.

  • It rotates freely in all directions

  • It can only rotate freely around one axis.

  • It can be found in the shoulder and hip joints.

  • It is located in the neck

10. Compare hinge joints with fixed joints.

Ans: Difference between hinge joints and fixed joints are as follows:

Hinge Joint

Fixed Joint

  • A hinge is formed when two bones are joined together.

  • It is an immovable/fixed joint formed when two bones come together.

  • Movement is limited to a single plane, with only back and forth movement allowed.

  • There is no movement at all.

  • It can be found in the elbow, knee, and other joints.

  • Found in the top section of the skull's bones.

FAQs on Important Questions for CBSE Class 6 Science Chapter 8 - Body Movements

1. Why do we need two muscles to move a bone according to Chapter 8 Class 6 Science?

Muscles and bones are important parts of the human body that need to work together. A human being can only move a bone with the help of two muscles. A muscle is known only to pull, not to push. Therefore, when one of the muscles contracts, a bone in the body is pulled. When the other muscle pulls, it helps to bring back the bone to its original position. Therefore, a human body requires at least two muscles in order to move a single bone in the body.

2. How does an earthworm move as described in Chapter 8 Class 6 Science?

Earthworms are tiny creatures that do not have any bones in them. Instead, these creatures are completely made up of muscles. While earthworms try to move, they first extend their front part of the body while keeping their rear part fixed on the ground. It then keeps its front part of the ground and then releases the rear part. It pulls the rear end forward while shortening its body. It repeats the contraction and expansion and ends up moving from one place to another.

3. What are the important questions of Chapter 8 Class 6 Science?

‘’Body Movements’’ is an important part of class 6 science. There are many important questions that are asked in this chapter. Students must know all the important definitions, and diagrams available in this chapter. These important questions of Chapter 8 Class 6 Science are picked from all the important concepts and topics available in this chapter. Students can access these important questions through Vedantu online portal and mobile app. Students can even download the PDF for free.

4. Why can our elbows not move backwards according to Chapter 8 Class 6 Science?

Our elbows are considered to be joints. In a joint, the end part of two bones is fixed together in the form of a hinge on a door. This in turn restricts the movement, extension, and flexion. Due to this, the movement of the joint takes place in one movement only. Since our elbows are considered joints, the elbow joint only permits movement in one direction. Therefore, our elbows can only move forward and not backwards.

5. What is cartilage according to Chapter 8 Class 6 Science?

Cartilage is a part of the skeleton. The parts that are additional in the skeleton, and the parts that are not as hard as the bones are known as cartilages. These cartilages are soft and elastic in nature. Since they are elastic, the cartilages can be bent towards any form, unlike bones that cannot be bent. Apart from this, Cartilages help to make some of the body parts of living organisms. An example is the cartilage of the ear.
