FAQs on The Skeletal System - Body Movements, Science, Class 7 Video Lecture
| 1. What are the main functions of the skeletal system? |  |
Ans. The main functions of the skeletal system are to provide support and shape to the body, protect vital organs, produce blood cells, store minerals, and enable movement.
| 2. How many bones are there in the human body? | |
Ans. The human body has a total of 206 bones.
| 3. What are the types of joints in the skeletal system? | |
Ans. The skeletal system consists of three main types of joints: fibrous joints, cartilaginous joints, and synovial joints. Fibrous joints allow little to no movement, cartilaginous joints allow limited movement, and synovial joints allow a wide range of movement.
| 4. What is the role of muscles in body movements? | |
Ans. Muscles work in conjunction with the skeletal system to facilitate body movements. When muscles contract, they pull on the bones, causing movement at the joints. Muscles are responsible for various types of movements, including bending, straightening, rotating, and extending body parts.
| 5. How does regular exercise benefit the skeletal system? | |
Ans. Regular exercise is beneficial for the skeletal system as it helps to strengthen bones and muscles. Weight-bearing exercises, such as walking or weightlifting, stimulate bone growth and increase bone density, reducing the risk of osteoporosis. Additionally, exercise helps improve joint flexibility, balance, and overall bone health.
