APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -In humans there are normally 12 pairs of ribs. The first seven pairs are attached directly to the sternum by costal cartilages and are called true ribs . The 8th, 9th, and 10th pairs-false ribs-do not join the sternum directly but are connected to the 7th rib by cartilage.

Detailed explanation-2: -The last two false ribs (11–12) are also called floating ribs (vertebral ribs). These are short ribs that do not attach to the sternum at all. Instead, their small costal cartilages terminate within the musculature of the lateral abdominal wall.

Detailed explanation-3: -Floating ribs can also be called the vertebral ribs. They don’t ventrally bind with the sternum but are only attached to the vertebral column. They are the very last two groups of ribs, the 11th and 12th pair, are known as the floating ribs.

Detailed explanation-4: -The next three pairs of bones are called false ribs. These bones are slightly shorter than the true ribs and are connected to the spine in back. However, instead of being attached directly to the sternum in front, the false ribs are attached to the lowest true rib.

Detailed explanation-5: -The false ribs are the ribs that indirectly articulate with the sternum, as their costal cartilages connect with the seventh costal cartilage; by the costochondral joint; They are the eighth, ninth, and tenth ribs.
