FAQs on Skeletal and Muscular System - 1 Class 5 Worksheet Science

1. What is the function of the skeletal system?
Ans. The skeletal system provides support, protection, and shape to the body. It also helps in movement by acting as an anchor for muscles and allows us to maintain an upright posture.
2. How many bones are there in the human body?
Ans. The human body has 206 bones. These bones vary in size and shape and are connected to each other by joints.
3. What are the different types of muscles in the muscular system?
Ans. The muscular system consists of three types of muscles: skeletal muscles, smooth muscles, and cardiac muscles. Skeletal muscles are attached to bones and help in voluntary movements. Smooth muscles are found in the walls of organs and blood vessels, and they control involuntary movements. Cardiac muscles are found only in the heart and are responsible for pumping blood.
4. How do muscles work together with the skeletal system?
Ans. Muscles and the skeletal system work together to allow movement. When a muscle contracts, it pulls on the bone it is attached to, causing movement at the joint. This coordinated action of muscles and bones allows us to perform various activities like walking, running, and lifting objects.
5. What happens to the skeletal and muscular systems as we age?
Ans. As we age, the skeletal system may become weaker and more prone to fractures due to decreased bone density. Muscles also tend to lose mass and strength, leading to decreased mobility and flexibility. Regular exercise and a balanced diet can help slow down these age-related changes and maintain healthy skeletal and muscular systems.
