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.
Ligament: fibrous connective tissue that holds the bones together. Open (loose) pack position: position with the least joint congruency where joint stability is reduced. Planes of movement: describe how the body moves. Up and down movements (flexion/extension) occur in the sagittal plane.
6 cze 2023 · Overview of the surface anatomy landmarks found on the thorax and upper limbs. 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.
14 lip 2023 · Articulations. Rib Fractures. Take the Quiz. 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.
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.
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.
6 gru 2023 · Rib Cage: Anatomy, Parts, Bones, Structures, Functions. The rib cage or thoracic cage (called thorax) is located in the most medial portion of the body and protects vital organs like the heart and lungs. The rib cage is an integral part of the axial skeleton in vertebrates and it lies in the thoracic cavity.
