The Ribs Anatomy

The rib cage is collectively made up of long curved individual bones with joint connections to the spinal vertebrae. They are twelve in number on either side.

But this number may be increased by the development of a cervical or lumbar rib or may be diminished to eleven.

The ribs anatomy. The ribs partially enclose and protect the chest cavity where many vital organs including the heart and the lungs are located. The typical ribs have a generalised structure while the atypical ribs have variations on this structure. The flexible hyaline cartilage makes the breathing process easier.

The head is wedge shaped and has two articular facets separated by a wedge of bone. The first seven are connected behind with the vertebral column and in front. The true ribs ribs 1 7 attach to the sternum by costal cartilages.

Ribs eight to ten are the false ribs and are connected to the sternum indirectly via the cartilage of the rib above them. Costæ the ribs are elastic arches of bone which form a large part of the thoracic skeleton. At the chest many rib bones connect to the sternum via costal cartilage.

The final two pairs of ribs are floating ribs and the cartilage of these ribs tends to end within the abdominal musculature. One facet articulates with the numerically corresponding vertebrae and the other articulates with the vertebrae above. The purpose of this video is to demonstrate the features of all 12 ribs starting with a description of a typical rib ribs 3 10.

There are twelve 12 pairs of ribs and all articulate posteriorly with the thoracic vertebrae. There are two classifications of ribs atypical and typical. The typical rib consists of a head neck and body.
