The terms true ribs and false ribs describe rib pairs that are directly or indirectly attached to the sternum respectively. The first seven rib pairs known as the fixed or vertebrosternal ribs are the true ribs (Latin: costae verae) as they connect directly to the sternum via their own individual costal cartilages.
The internal intercostal muscles (intercostales interni) are a group of skeletal muscles located between the ribs.They are eleven in number on either side. They commence anteriorly at the sternum, in the intercostal spaces between the cartilages of the true ribs, and at the anterior extremities of the cartilages of the false ribs, and extend backward as far as the angles of the ribs, hence ...
In reference to the muscles of the thoracic wall, the intercostal nerves and vessels run posterior to the internal intercostal muscles: therefore, they are generally covered on the inside by the parietal pleura, except when they are covered by the innermost intercostal muscles, innermost intercostal membrane, subcostal muscles or the transversus thoracis muscle.
Unlike costochondritis, the pain associated with slipping rib syndrome is often felt in the lower ribs, abdomen, and back, commonly affecting the interchondral junctions of the false 8th to 10th ribs. [18] [19] Costochondritis is typically experienced within the sternocostal junctions of the true 2nd to 5th ribs.
3D medical animation still shot of human skull. The axial skeleton is the core part of the endoskeleton made of the bones of the head and trunk of vertebrates.In the human skeleton, it consists of 80 bones and is composed of the skull (28 bones, including the cranium, mandible and the middle ear ossicles), the vertebral column (26 bones, including vertebrae, sacrum and coccyx), the rib cage ...
The sternocostal joints, also known as sternochondral joints or costosternal articulations, are synovial plane joints of the costal cartilages of the true ribs with the sternum. [1] The only exception is the first rib , which has a synchondrosis joint since the cartilage is directly united with the sternum. [ 1 ]

The rib cage consists of 12 pairs of ribs including the true ribs (1st to 7th), false ribs (8th to 10th), and the floating ribs (11th and 12th). The true ribs are directly connected to the sternum by the costal cartilage. Similarly, the false ribs also connect to the sternum through costal cartilages, however indirectly through a connection to ...
