This article discusses the key anatomical structures of the thoracic vertebrae and rib cage, including the bony structures, articulations, ligaments, muscles, nerves and the vascular supply. Key Terms [edit | edit source] Axes: lines around which an object rotates. The rotation axis is a line that passes through the centre of mass.
The rib cage or thoracic cage is an endoskeletal enclosure in the thorax of most vertebrates that comprises the ribs, vertebral column and sternum, which protect the vital organs of the thoracic cavity, such as the heart, lungs and great vessels and support the shoulder girdle to form the core part of the axial skeleton.
6 cze 2023 · The thoracic cage, also known as the rib cage, is the osteocartilaginous structure that encloses the thorax. It is formed by the 12 thoracic vertebrae, 12 pairs of ribs and associated costal cartilages and the sternum.
12 gru 2023 · Ribs (12, paired): These elongated, curved, flat bones enclose the anterior aspect of the thoracic basket. Out of the 12 paired bones, the first 7 pairs articulate with the sternum via their respective costal cartilages. The space between two ribs is termed the intercostal space.
The thoracic cage (rib cage) forms the thorax (chest) portion of the body. It consists of the 12 pairs of ribs with their costal cartilages and the sternum (Figure 7.5.1). The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1–T12). The thoracic cage protects the heart and lungs.
14 lip 2023 · The ribs are a set of twelve paired bones which form the protective ‘cage’ of the thorax. They articulate with the vertebral column posteriorly, and terminate anteriorly as cartilage (known as costal cartilage). As part of the bony thorax, the ribs protect the internal thoracic organs.
2 lis 2022 · Introduction to the Structure of the Ribcage and Ribs: There are twelve (12) pairs of ribs and all articulate posteriorly with the thoracic vertebrae. Lateral view of a pair of ribs articulating with the thoracic vertebrae. The true ribs (ribs 1-7) attach to the sternum by costal cartilages.
