Question

Let's identify our bones.

1. What is the name of the hard part you feel on placing your hand on your chest?
2. Do you feel some hard bumps on the back? What are they called?
3. What difference do you notice between the bones of the back and those of the chest?

Answer 1

1. The hard part at the centre of the chest is called the breastbone or sternum.
2. Yes, we can feel some hard bumps along the centre of the back. They are called vertebrae. Together, they form the backbone or vertebral column.
3. The bones of the backbone are small and arranged one above another, forming a flexible chain. The breastbone is a broad, flat bone present at the centre of the chest and is connected with the ribs.
