What is the coastal angle is?
The costal angle is the angle beneath the the sternum. It is created by the costal cartilage that joins what are called the false ribs, the ones tha6t do not directly attach to the sternum via their own cartilage, but attach directly and indirectly to the cartilage of the 7th rib. This angle is created because these false ribs get shorter as they go down. Since they are connected by the descending costal cartilage which travels laterally and inferiorly from the sternum, it creates the angle known as the costal angle.
How are the ribs classified on the basis of their attachment to the sternum?
Ribs are classified according to their attachment to the sternum. The first seven pairs of ribs attach directly to the sternum and are called true ribs. Ribs 8-10 have cartilage that attaches to the cartilage of the seventh rib and are called false ribs. The eleventh and twelfth ribs do not attach to the sternum and are called floating ribs.
What is the cartilage found at the end of the ribs?
The cartilage found at the end of the ribs is called costal cartilage. It helps to attach the ribs to the sternum (breastbone) and allows for flexibility and movement during breathing.
Which ribs do not attach anteriorly to the sternum?
Ribs 11 and 12 do not attach anteriorly to the sternum.
Are the first seven pairs of ribs considered false because of their posterior and direct anterior attachments?
Yes, the first seven pairs of ribs are considered false ribs because they do not attach directly to the sternum but rather either indirectly or not at all. They connect to the sternum through cartilage or do not connect at all in the case of floating ribs.
What is the purpose of the xiphoid process?
The function of the xiphoid process is to attach the cartilage in the celiac plexus to the sternum. It also indirectly attaches the costal cartilage to the sternum.

Ribs that do not attach to coastal cartilage at all are?
they are defined as floating ribs
How do ribs attach to the sternum in a horse?
hyaline cartilage... that's the 10 pairs. not sure on the first eight pairs
What is the cartilage found at the end of the ribs?
The cartilage found at the end of the ribs is called costal cartilage. It helps to attach the ribs to the sternum (breastbone) and allows for flexibility and movement during breathing.
What is the importance of costal cartilage?
Costal cartilage allows more ribs to attach to the sternum, albeit indirectly, for a more stable and secure ribcage to protect the heart and lungs.
The difference between a true ribe and a false ribe?
True ribs attach with the cartilage that is a direct bridge to the sternum; they are called true ribs or vertebro-sternal ribs The false ribs just attach to cartilage that bind into one link or bridge that connects with the sternum (almost looks like a little web)
Which ribs do not attach anteriorly to the sternum?
Ribs 11 and 12 do not attach anteriorly to the sternum.

What are some causes for arthritis in the breastbone?
This type of arthritis refers to the inflammation of the cartilage where ribs attach to the breastbone, or the sternum. Heredity, viruses or injury may cause it.
What connects the ribs to the sternum?
The true ribs (pair 1-7) are connected to the sternum by way of the costal cartilages, a type called hyaline. Pair 8-10 are called floating ribs and they also attach to the sternum but use the same cartilage as 7.
