Solution:

Ribs are of 3 types:
1. True ribs (First 7 pairs) :Dorsally attached to the thoracic vertebrae and ventrally connected to the sternum with the help of hyaline cartilage.
2. Vertebrochondral or False ribs (8th, 9th and 10th pairs): These ribs do not articulate directly with the sternum but join the 7th rib with the help of hyaline cartilage.
3. Floating ribs (11th and 12th pairs): These ribs are not connected ventrally.
