Test: Skeletal & Muscular System - 1 - Class 5 MCQ

• The femur is the longest bone in our body. It is located in the upper leg, also known as the thigh.
• This bone is very strong and helps us to stand, walk, and run.
• It is like the pillar that holds up our body.
• So, the statement is True!
• Remember, the femur is super important for our body to move and stay strong.

We need bones in our body to protect our internal organs like the heart, lungs, and brain. Just like how a shield protects a warrior in a battle, our bones protect the important parts inside us. They make sure our organs are safe and can work properly.

• In our bodies, muscles work by pulling on bones, not by pushing them. This means muscles can only make movements by pulling on bones, not by pushing them. So, the statement that muscles can push bones to make them move is False.
• Imagine your muscles are like a rope that pulls your bones to help you move. They can't push like you push a toy car, they only pull to help you run, jump, and play!

A place where two bones meet is called a joint. Ligaments are strong, elastic bands of tissue that join bones together to form a joint, helping us to bend, twist, and turn easily.

The human body has a framework of bones known as a skeleton. The skeleton provides support to our body and protects our internal organs.

Muscles in our body work by pulling on bones. Imagine you have a rubber band and you pull it to make it stretch. Similarly, muscles pull on our bones to help us move. So, when you bend your arm or move your leg, it's the muscles pulling on your bones that make it happen.
