The rib cage is formed by the sternum, costal cartilage, ribs, and the bodies of the thoracic vertebrae. The rib cage protects the organs in the thoracic cavity, assists in respiration, and provides support for the upper extremities.

Anatomical terminology In vertebrate anatomy, ribs (Latin: costae) are the long curved bones which form the rib cage, part of the axial skeleton. In most tetrapods, ribs surround the chest, enabling the lungs to expand and thus facilitate breathing by expanding the chest cavity.

Each rib is a curved, flattened bone that contributes to the wall of the thorax. The ribs articulate posteriorly with the T1–T12 thoracic vertebrae, and most attach anteriorly via their costal cartilages to the sternum. There are 12 pairs of ribs. The ribs are numbered 1–12 in accordance with the thoracic vertebrae.

Define the parts and functions of the thoracic cage. The thoracic cage is formed by the 12 pairs of ribs with their costal cartilages and the sternum. The ribs are attached posteriorly to the 12 thoracic vertebrae and most are anchored anteriorly either directly or indirectly to the sternum.

functions: separates the abdominal and thoracic cavities and it draws air into the lungs. function: pumping chambers of the heart; the right side pumping oxygen-poor blood to the lungs and the left side pumping oxygen-rich blood to the body.

Ribs are long, curved bones that form the rib cage surrounding the thorax. The thoracic cage can expand and contract to facilitate breathing in association with the diaphragm; it also protects the lungs, heart, and other organs of the thoracic cavity.

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 main function of this chest muscle as a whole is the adduction and internal rotation of the arm on the shoulder joint. Acting independently, the clavicular part helps to flex the extended arm up to 90°, while the sternocostal part facilitates the extension of the flexed arm by pulling it downwards.

Solution: False ribs are the ribs which are not directly attached to the sternum (8th – 10th pair). The main function of the costal cartilage is to serve as a medium for attachment to sternum. As it is cartilage it can expand thus gives lungs a greater intake capacity.

Baby back ribs come from the parts of the ribs that are connected to the backbone, beneath the loin muscle, and are curved where the meet the spine. They're called “babies” because they're shorter than spare ribs; on the longest end, they're around 6 inches, and they taper down to about 3 inches on the shorter end.

Ribs 11 and 12 are called "floating ribs" simply because they do not articulate or are attached to the sternum. The sternum, which is made of three parts: the manubrium, the body, and the xiphoid process, is the long flatbone located at the center of the chest.

The main bones in the abdominal region are the ribs. The rib cage protects vital internal organs. There are 12 pairs of ribs and they attach to the spine. There are seven upper ribs, known as “true” ribs, which attach to the sternum (breastbone) in the front of body.
