Where are ribs 10 and 11 located?
Ribs 8–10 are attached indirectly to the sternum. For these ribs, the costal cartilage of each attaches to the cartilage of the next higher rib. The last false ribs (11–12) are also called floating (vertebral) ribs, because these ribs do not attach to the sternum at all.
What bone is just above the rib cage?
sternum
The sternum is a long, flat bone that’s located in the middle of your chest.
Where is the rib cage bone located?

The rib cage is collectively made up of long, curved individual bones with joint-connections to the spinal vertebrae. At the chest, many rib bones connect to the sternum via costal cartilage, segments of hyaline cartilage that allow the rib cage to expand during respiration.
What are 3 types of ribs?
According to their attachment to the sternum, the ribs are classified into three groups: true, false, and floating ribs.
What are the 12 pairs of ribs?
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.
Where is 8th rib located?
These ribs, known as true ribs, also connect to your spine in the back. The 8th, 9th, and 10th rib pairs don’t connect directly to your sternum, but they are connected to each other by cartilage that attaches to the costal cartilage of the 7th rib pair. These ribs also attach to your spine in the back.
What is the name of the wrist bones?
Your wrist is made up of eight small bones called the carpal bones, or the carpus. These irregularly shaped bones join your hand to the two long forearm bones: the radius and ulna. The carpal bones are small square, oval, and triangular bones.
Which rib is closest to the heart?
1. The inferior tip of the heart, the apex, lies just to the left of the sternum between the junction of the fourth and fifth ribs near their articulation with the costal cartilages.
Whats behind the rib cage?
Their function is to protect your organs that lie beneath them. On the left side, this includes your heart, left lung, pancreas, spleen, stomach, and left kidney. When any of these organs are infected, inflamed, or injured, pain can radiate under and around your left rib cage.
Which type of rib breaks most easily?
The middle ribs are most commonly fractured. Fractures of the first or second ribs are more likely to be associated with complications.
