What are the muscles located between the ribs called?

The muscles located between the ribs are called intercostal muscles. These muscles play a crucial role in the respiratory process by aiding in the expansion and contraction of the rib cage. When you inhale, the intercostal muscles contract and elevate the ribs, allowing the lungs to expand and fill with air. Conversely, during exhalation, these muscles relax, which helps to lower the rib cage and push air out of the lungs.

The other options refer to different muscle groups or functions. Abdominal muscles are located in the front of the abdomen and primarily assist in torso movements and stabilization. Skeletal muscles encompass a broad category of muscles responsible for voluntary movements, including those involved in body locomotion, but do not refer specifically to the muscles between the ribs. The diaphragm muscles, while crucial for respiration, are a separate muscle located beneath the lungs that contracts and relaxes to facilitate breathing rather than being situated between the ribs.
