Introduction to the structure of the ribcage and ribs. In humans the rib cage also known as the thoracic cage is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the shoulder girdle to form the core part of the human skeleton.
The Human Ribcage How It Works
The true ribs ribs 1 7 attach to the sternum by costal cartilages.
Human anatomy ribs. The rib cage shaped in a mild cone shape and more flexible than most bone sets is made up of varying elements such as the thoracic vertebra 12 equally paired ribs costal cartilage and held together anteriorly by the sternum. A typical human rib cage consists of 24 ribs in 12 pairs the sternum and xiphoid process the costal cartilages and the 12 thoracic vertebrae. Of all 24 ribs the first seven pairs are often labeled as true these bones are connected to the costal cartilage while the five other false sets are not.
Ribs are classed as flat bones which usually have a protective role in the body. The primary responsibilities of the ribcage involve protecting the thoracic visceral organs. Humans have 24 ribs in 12 pairs.
Rib pairs one through seven are called true ribs because they attach directly to the sternum. There are two classifications of ribs atypical and typical. There are twelve 12 pairs of ribs and all articulate posteriorly with the thoracic vertebrae.
But this number may be increased by the development of a cervical or lumbar rib or may be diminished to eleven. The typical ribs have a generalised structure while the atypical ribs have variations on this structure. Costæ the ribs are elastic arches of bone which form a large part of the thoracic skeleton.
Rib pairs eight through ten attach indirectly through other cartilage structures so theyre referred to as false ribs. Human anatomy rib details. The head is wedge shaped and has two articular facets separated by a wedge of bone.
The final two pairs the floating ribs hang unattached to the sternum. Three of those connect to non costal cartilage. All are attached at the back to the thoracic vertebrae and are numbered from 112 according to the vertebrae they attach to.

The human rib cage is made up of 12 paired rib bones. Each are symmetrically paired on a right and left side.
Or rather most of them do. The typical rib consists of a head neck and body. The first seven are connected behind with the vertebral column and in front.
They are twelve in number on either side. One facet articulates with the numerically corresponding vertebrae and the other articulates with the vertebrae above. Lateral view of a pair of ribs articulating with the thoracic vertebrae.
The first rib is attached to thoracic vertebra 1 t1.
