Which rib attaches directly to the sternum?
Which rib attaches directly to the sternum?
True ribs
True ribs (1–7) attach directly to the sternum via their costal cartilage. The false ribs (8–12) either attach to the sternum indirectly or not at all. Ribs 8–10 have their costal cartilages attached to the cartilage of the next higher rib.
Is the sternum attached to the spine?
The thoracic cage protects the heart and lungs. It is composed of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae. The sternum consists of the manubrium, body, and xiphoid process.
Is spine attached to the ribs?
In addition to being connected to adjacent vertebrae, the thoracic vertebrae are also connected to ribs. The cervicothoracic junction is where the neck (cervical spine) connects with the upper back (thoracic spine).
Which type of rib does not connect 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 is the difference between sternum and vertebral column?
The vertebral column consists of 24 bones, each called a vertebra, plus the fused vertebrae of the sacrum and coccyx. The thoracic cage includes 12 pairs of ribs, and the sternum, the flattened bone of the anterior chest.
Which bone is between your spine and femurs?
The left and right hip bones meet anteriorly at the body’s midline in a band of fibrocartilage known as the pubic symphysis (or symphysis pubis). The hip bones also form the ball-and-socket hip joints with the femurs.
Which type of rib does not connect to the sternum quizlet?
The 8th, 9th, and 10th pairs— false ribs—do not join the sternum directly but are connected to the 7th rib by cartilage. You just studied 7 terms!
What is the sternum to the vertebral column?
The breastbone is ANTERIOR to the spine. The sternum is ANTERIOR to the heart. EX: The heart is SUPERIOR to the diaphragm.
How are the ribs connected to the sternum?
Ten of the twelve ribs connect to strips of hyaline cartilage on the anterior side of the body. The cartilage strips are called costal cartilage (“costal” is the anatomical adjective that refers to the rib) and connect on their other end to the sternum. On an individual rib, one end has various processes, facets, and bumps.
How are the ribs connected to the thoracic cage?
The rib below that is rib 2, and it connects to the T2 thoracic vertebra, and so on. Ten of the twelve ribs connect to strips of hyaline cartilage on the anterior side of the body. The cartilage strips are called costal cartilage (“costal” is the anatomical adjective that refers to the rib) and connect on their other end to the sternum.
How are the ribs related to the vertebra?
On an individual rib, one end has various processes, facets, and bumps. This is the end that articulates with the vertebra. The other end is blunt and smooth. This is the end that connects to costal cartilage (unless it is a floating rib. See below.) Ribs 1-7 are called the true ribs.
How are ribs attached to the costal cartilages?
Ribs 8 – 10 attach to the costal cartilages superior to them. Ribs 11 and 12 do not have an anterior attachment and end in the abdominal musculature. Because of this, they are sometimes called ‘floating ribs’. Rib fractures most commonly occur in the middle ribs, as a consequence of crushing injuries or direct trauma.
