Answer the Following Questions.

Question 1.
Write short notes on different types of joints in our body.
Answer:
1. The point where two bones meet is called a joint.
2. Joints are of two types. They are movable and immovable (fixed).
3. Movable joints are four types namely 1. Ball and socket 2. Hinge 3. Sliding 4. Pivot
joints.

1. Ball and socket: The rounded end of one bone fits into the hollow end of the other bone. Such a joint allows movement in all directions. This joint is known as the ball and socket joint. It is present at the shoulder and at the hip region.
   
2. Hinge joint: Like the hinge of a door, the joint which helps the bones to move in one direction is called a hinge joint. These are present at the elbow and knee.

Question 2.
What are the uses of muscles and bones?
Answer:

1. Muscles helps in the locomotion and movements of the body, they also provide shape and structure to the body.
2. Bones provide a base to muscles. They have a key role in body movements and the shape of the body.

Question 3.
Differentiate the ball and socket joint from the hinge joint.
Answer:

Question 4.
How is the body of a fish suitable for swimming?
Answer:

1. The skeleton of the fish is covered with strong muscles.
2. While swimming,-muscles make the front part of the body swing towards one side while the tail swings its body towards the opposite.
3. This creates a jerk and pushes the body forward.
4. A series of such jerks help the fish swim forward.
5. The tail fins also aid in this movement.

Question 5.
Guess who I am?
i) I am a joint that works like a joint of doors and windows.
Answer:
Hinge joint.

ii) I help to join two bones.
Answer:
Ligament.

iii) I am a joint between the upper jaw and skull.
Answer:
Fixed joint.

iv) I am a chain of small-small bones.
Answer:
Vertebral column or backbone.

v) I join the bone and muscle.
Answer:
Tendon.

Question 6.
What would happen if there are no bones and joints in our body?
Answer:
If there are no bones and joints in our body

1. we do not have a particular body shape,
2. movements and locomotions are not possible.
3. Simply we become round as mass body.

Question 7.
What would happen if there is a single bone in your fingers?
Answer:
If we have a single bone in our fingers.

1. we can’t fold the fingers.
2. we can’t catch or hold anything.
3. it becomes hard to get food.
4. we cant manage any apparatus.
5. in the evaluation, we become so backward.

Question 8.
Draw a neat and labeled diagram of the Ball and socket joint and write its location and uses.
Answer:

These joints are located in the shoulders and hip region. It is used in swinging and rotating movements.

Question 9.
How do you appreciate locomotion in birds?
Answer:
I feel wonder about flying of birds.
They have wonderful wings and attractive feathers. Birds are only creatures that fly easy to escape.
This feature also help them in long journey to migrate. I feel its beautiful if I have wings to fly.
