Each are symmetrically paired on a right and left side.

Human rib anatomy. Of all 24 ribs the first seven pairs are often labeled as true. They are twelve in number on either side. The sternum also called the breastbone is located in the middle of your chest and it is.

Human anatomy rib details. Rib cage anatomy 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. Sternal end region of the rib that attaches to the costal cartilage.

Rib pairs one through seven are called true ribs because they attach directly to the sternum. Ribs are classed as flat bones which usually have a protective role in the body.

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. The rib cage the rib cage or thoracic basket consists of the 12 thoracic chest vertebrae the 24 ribs and the breastbone or sternum.

Or rather most of them do. Together with the skin and associated fascia and muscles the rib cage makes up the thoracic wall and provides attachments for the muscles of the neck thorax upper abdomen and back. The first rib is attached to thoracic vertebra 1 t1.

Role in human skeletal protective system. Rib pairs eight through ten attach indirectly through other cartilage structures. The thoracic or rib cage is comprised of 3 main parts the sternum the ribs and the thoracic vertebrae.

The cartilage portions of the ribs meet in the front at the long flat three bone plate called the sternum breastbone. In human skeletal system the bony thoracic basket or rib cage which forms the skeleton of the wall of the chest or thorax. Humans have 24 ribs in 12 pairs.

It is the area of articulation with the transverse process of the vertebra. Costæ the ribs are elastic arches of bone which form a large part of the thoracic skeleton. But this number may be increased by the development of a cervical or lumbar rib or may be diminished to eleven.

In human skeletal system. Tubercle small elevation on the posterior surface of the rib at the junction of the head and neck. Medial view of the tubercle of the right ribs.
