The intercostal space (ICS) is the anatomic space between two ribs (Lat. costa). Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it. Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it.
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.
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 ...
The first seven pairs are connected with the sternum; the next three are each articulated with the lower border of the cartilage of the preceding rib; the last two have pointed extremities, which end in the wall of the abdomen. [2] Like the ribs, the costal cartilages vary in their length, breadth, and direction. They increase in length from ...
The intercostal veins are a group of veins which drain the area between the ribs ("costae"), called the intercostal space. They can be divided as follows: Anterior intercostal veins; Posterior intercostal veins. Posterior intercost vein that drain into the Supreme intercostal vein - 1st intercostal space
In between the rib bones are the intercostal muscles, Vasudevan adds, which allow the chest to move. ... A hard cough or sneeze can also cause pain in the space under your right rib cage. Severe ...
Internal intercostal muscles also known as intercostalis internus aid in forced expiration (quiet expiration is a passive process). They originate on ribs 2–12 and have their insertions on ribs 1–11.Their fibers pass anterior and superior from the upper margin of the rib and costal cartilage to the lower margin of the rib above.

The first rib is attached to thoracic vertebra 1 (T1). At the front of the body, most of the ribs are joined by costal cartilage to the sternum. Ribs connect to vertebrae at the costovertebral joints. [4] The parts of a rib includes the head, neck, body (or shaft), tubercle, and angle. The head of the rib lies next to a vertebra. The ribs ...
