elevation
not sure there is a term, but by expanding your rib cage, you create negative pressure in your chest cavity, which pulls in air via your mouth and nose to fill the void.
I think it would be elevation, but I agree - there is no specific term that i learned in school for that specifically.
The general term for raising anything is called "elevation."
The ribs enclose the thoracic cavity providing bony protection for the vital organs of the thorax-the heart and lungs.Because the thorax must expand and contract to allow breathing, the ribs move slightly in a "bucket handle" type of motion with each breath.Therefore the ribs are involved with breathing.
The nervous system controls the movement of the ribs during breathing. The movement is performed by the musculoskeletal system.
Diaphragm
Clavicular breathing relates to the Clavicle/collar bone, it is said to be the worst type of breathing which is a shallow inhalation which raises the collar bone and abdoman. The Thoracic breathing is essentialy breathing from the ribs where the rib muscles expand the ribs and chest.
Ribs move with the diaphragm to assist in breathing. While they are fairly rigid, just look at how your chest expands and contracts while breathing. If they were immovable, there would be no movement.
If the head of the neck is fixed, then it is possible for the muscles to raise the clavicle and manubrium sterni, and hence the ribs, so that they act as accessory muscles of respiration.

The ribs are linked by the intercostal muscles. These open and close the ribcage to cause breathing.
