Question

Write a short note on Rib cage with a neat labelled diagram.

Answer 1

Rib cage:
Rib cage occupies the chest region. It is a cone-shaped structure made up of 12 pairs of ribs. Ribs are attached to vertebrae at the back which curve around to form a cage.

• 10 pairs of ribs are attached to the breast bone at the front. 2 pairs of lower ribs are free at front. These are called as free-floating ribs.
• Rib cage is set up in such a way that it can contract and expand during the process of breathing. Rib cage protects the underlying lungs, heart and some part of liver.
