Question

Match the following:
$\begin{array}{cc}\text{Type of ribs}& \text{Location}\\ \text{1. True ribs}& \text{a. 8th, 9th and 10th pair}\\ \text{2. False ribs}& \text{b. 11th and 12th pair}\\ \text{3. Floating ribs}& \text{c. First 7 pairs}\end{array}$

• A. 1-a, 2-b, 3-c
• B. 1-a, 2-c, 3-b
• C. 1-c, 2-b, 3-c
• D. 1-c, 2-a, 3-b

Answer 1

The correct option is D 1-c, 2-a, 3-b

There are 12 pairs of ribs. Each rib is connected dorsally to the vertebral column and ventrally to the sternum. First seven pairs of ribs are called true ribs. Dorsally, they are attached to the thoracic vertebrae and ventrally connected to the sternum with the help of hyaline cartilage.
The 8th, 9th and 10th pairs of ribs do not articulate directly with the sternum but join the seventh rib with the help of hyaline cartilage. These are called false ribs.
Last 2 pairs or the11th and 12th of ribs are not connected ventrally and are therefore, called floating ribs
