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.
Rib. In vertebrate anatomy, ribs (Latin: costae) are the long curved bones which form the rib cage, part of the axial skeleton. [1] In most tetrapods, ribs surround the thoracic cavity, enabling the lungs to expand and thus facilitate breathing by expanding the thoracic cavity. They serve to protect the lungs, heart, and other vital organs of ...
Liver shot. A left hook to the liver. A liver shot or liver punch is a punch, kick, or knee strike to the right side of the ribcage that damages the liver. Blunt force to the liver can be excruciatingly painful, and an especially effective shot will incapacitate a person instantly. [1] Thus, in combat sports, liver shots often result in ...
The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum. There are two openings of the thoracic cavity, a superior thoracic aperture known as the thoracic inlet and ...
Slipping rib syndrome. Slipping rib syndrome (SRS) is a condition in which the interchondral ligaments are weakened or disrupted and have increased laxity, causing the costal cartilage tips to subluxate (partially dislocate). This results in pain or discomfort due to pinched or irritated intercostal nerves, straining of the intercostal muscles ...
Abdominopelvic cavity. The abdominopelvic cavity is a body cavity that consists of the abdominal cavity and the pelvic cavity. [1] The upper portion is the abdominal cavity, and it contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, small intestine, and most of the large intestine. The lower portion is the pelvic cavity, and it ...
The muscles of respiration are the muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity. The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing. The elasticity of these muscles is crucial to the health of the respiratory system ...
The liver, viewed from above, showing the left and right lobes separated by the falciform ligament. The liver is a dark reddish brown, wedge-shaped organ with two lobes of unequal size and shape. A human liver normally weighs approximately 1.5 kilograms (3.3 pounds) [11] and has a width of about 15 centimetres (6 inches). [12]
