Detailed explanation-1: -The lower five pairs of ribs (ribs eight to twelve) are known as false ribs because their costal cartilages do not articulate directly with the sternum.
Detailed explanation-2: -Because the last three pairs of ribs, the 8th, 9th, and 10th pairs, do not directly articulate with the sternum, they are referred to as false ribs. They connect the 7th rib’s cartilaginous components.
Detailed explanation-3: -The first seven pairs of ribs 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. The 11th and 12th (2 pairs)-floating ribs.
Detailed explanation-4: -The first five ribs are termed true ribs because they attach directly to the sternum through the costal cartilage. The next five ribs are termed false ribs because they attach to the sternum indirectly through the costal cartilage.
Detailed explanation-5: -Ribs 1–7 are classified as true ribs (vertebrosternal ribs). The costal cartilage from each of these ribs attaches directly to the sternum. Ribs 8–12 are called false ribs (vertebrochondral ribs). The costal cartilages from these ribs do not attach directly to the sternum.
