Question

How many ribs does the human body have? What are "false" ribs?

Answer 1

Ribs:

1. There are 12 pairs of ribs in the human chest, each of which is a thin flat bone attached to the spinal column dorsally and the sternum ventrally.
2. The human body contains bicephalic ribs. They get their name from the fact that their dorsal end has two articulation surfaces.
3. True ribs are the first seven pairs of ribs among the 12 pairs of ribs.
4. The ribs are attached to the thoracic vertebrae dorsally and to the sternum ventrally via hyaline cartilage.

False ribs:

1. 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.
2. They connect the 7th rib's cartilaginous components.
3. The last two pairs of ribs, the 11th, and 12th pairs are called floating ribs because they are not attached ventrally to the sternum or the anterior ribs.
4. False ribs are the last five pairs of ribs that are not immediately linked to the sternum.
