Rib cage how many ribs




















Ribs 8—12 are called false ribs vertebrochondral ribs. The costal cartilages from these ribs do not attach directly to the sternum. For ribs 8—10, the costal cartilages are attached to the cartilage of the next higher rib. Thus, the cartilage of rib 10 attaches to the cartilage of rib 9, rib 9 then attaches to rib 8, and rib 8 is attached to rib 7.

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. Skip to main content. Chapter 6: The Skeletal System. Search for:. Instead, costal cartilage anchors them to the ribs above them. They collectively share a cartilage connection to the sternum by blending into the cartilage of rib 7.

These ribs also connect to the thoracic vertebrae in the back. Sets 11 and 12 are floating ribs, and they only connect to the thoracic vertebrae of the spinal column in the back. It is the flexible costal cartilage that allows the ribs to expand when people take deep breaths. Supernumerary ribs occur in about 0. Typically, they develop on the last vertebra of the neck the 7th cervical vertebra above the normal first rib.

They are called cervical ribs, and they usually develop in pairs, although some people may only have one cervical rib. Much of the time, cervical ribs do not cause any symptoms. However, they can press on and constrict nerves and blood vessels, which can create a condition called thoracic outlet syndrome.

Although many people might think that males have fewer ribs than females — most likely sparked by the biblical story of Adam and Eve — there is no factual evidence.

In addition to scoliosis and fused or misshapen vertebrae, people born with this condition may have ribs that are fused together, or missing entirely. Spondylothoracic dysplasia is an autosomal recessive condition. Babies born with this condition have fused ribs and fused vertebrae. They also have very small chest cavities, which can cause severe problems with breathing.

Goldenhar syndrome is a rare congenital condition that causes anomalies to occur in the spine, ears, and eyes. Babies born with Goldenhar syndrome may have one or two partially formed or missing ears, and benign eye growths.

They may also have an underdeveloped jaw and cheekbone, and ribs that are missing, fused, or not fully formed. Some rib deformities may be picked up via ultrasound, before your baby is born. Others may become apparent after birth, if your baby has a smaller chest size, or displays difficulty with breathing. If so, treatment will focus on respiratory support. Missing ribs are sometimes corrected surgically with a device called a vertical expandable prosthetic titanium rib VEPTR.

VEPTRs can be adjusted in size as your child grows. If there are no problems with posture, breathing, or walking, watchful waiting may be all that is required.
