What is the thorax?

(THOR-ax) The area of the body between the neck and the abdomen. The thorax contains vital organs, including the heart, major blood vessels, and lungs. It is supported by the ribs, breastbone, and spine. A thin muscle called the diaphragm separates the thorax from the abdomen.

What parts make up the thorax?

The bony framework of the human thorax consists of the 12 thoracic vertebrae, 12 pairs of ribs, and the sternum (breastbone).

How many ribs are in thoracic?

The rib cage surrounds the lungs and the heart, serving as an important means of bony protection for these vital organs.In total, the rib cage consists of the 12 thoracic vertebrae and the 24 ribs, in addition to the sternum.

What organ is between your ribs?

The liver is located under the ribs on the right hand side of the body. It lies just below the lungs, under the top of the diaphragm to which it is attached. The diaphragm is the muscle beneath the lungs which regulates our breathing. The liver is partly protected by the rib cage.

What is the major function of the thorax cage?

The thoracic cage is formed by the 12 pairs of ribs with their costal cartilages and the sternum. The ribs are attached posteriorly to the 12 thoracic vertebrae and most are anchored anteriorly either directly or indirectly to the sternum. The thoracic cage functions to protect the heart and lungs.

Why is the thoracic cage important?

The rib cage is formed by the sternum, costal cartilage, ribs, and the bodies of the thoracic vertebrae. The rib cage protects the organs in the thoracic cavity, assists in respiration, and provides support for the upper extremities.

What are the 3 types of ribs?

According to their attachment to the sternum, the ribs are classified into three groups: true, false, and floating ribs.

The chest, properly called the thorax, is the superior part of the trunk located between the neck and abdomen. It consists of several components: Thoracic wall.

What is the rib cage?

The rib cage consists of 24 ribs (2 sets of 12), which are attached to a long, flat bone in the centre of the chest called the sternum. The ribs are connected to the sternum with a strong, somewhat flexible material called cartilage.

Where is the thoracic region located?

Your thoracic spine is the middle section of your spine. It starts at the base of your neck and ends at the bottom of your ribs. It’s the longest section of your spine. Your thoracic spine consists of 12 vertebrae, labeled T1 through T12.

What are ribs 1/7 called?

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.

What are the 8 through 12 ribs called?

Ribs 1-7 are called the true ribs. Each true rib connects to its own strip of costal cartilage, which in turn connects to the sternum. Ribs 8-12 are called the false ribs.

Where is the 8th rib?

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.

Why are ribs 8/12 considered false ribs?

Rib pairs 8-12 are considered false ribs because they only attach to the sternum by attaching their combined costal cartilages with the costal cartilage of the 7th rib.

The Anatomy of a Floating Rib

The last two pairs of ribs at the very bottom of the rib cage do not attach to the sternum at all. These ribs are referred to as “floating ribs” as their only attachment is found at the back of the rib cage, anchored to the vertebrae of the spine.

What are floating ribs called?

Floating ribs are also known as vertebral ribs. They do not connect with the sternum ventrally and are only connected to the vertebral column.

Why does my bottom left rib stick out?

Rib flare is a condition that’s caused by poor training and bad habit, where the bottom ribs protrude rather than being tucked into the body. There’s no pain or injury associated with this condition, but the habit itself can inhibit an athlete’s performance and make them more susceptible to injury.

Is there a bone at the bottom of your rib cage?
