FAQs on Bones, Muscles and Postures - 2 Class 2 Worksheet Science

1. What are the main bones in the human body?
Ans.The main bones in the human body include the skull, spine, ribs, and limbs. The adult human skeleton consists of 206 bones, which provide structure, protect vital organs, and allow for movement.
2. How do muscles work with bones to enable movement?
Ans.Muscles are attached to bones via tendons. When muscles contract, they pull on the bones, creating movement at the joints. This coordinated action between muscles and bones allows for various physical activities such as walking and running.
3. What is good posture and why is it important?
Ans.Good posture refers to the alignment of the body in a way that puts the least amount of strain on supporting muscles and ligaments. It is important because it helps prevent pain, reduces the risk of injury, and improves overall body function.
4. How can I improve my posture while sitting at a desk?
Ans.To improve posture while sitting at a desk, make sure your feet are flat on the floor, your back is straight against the chair, and your computer screen is at eye level. Take regular breaks to stretch and adjust your position to avoid slouching.
5. What exercises can strengthen my muscles and support good posture?
Ans.Exercises like planks, bridges, and back extensions can strengthen core muscles, which support good posture. Additionally, activities such as yoga and Pilates focus on flexibility and strength, promoting better alignment and body awareness.
