The intercostal muscles are a group of 22 pairs of tiny muscles found between the ribs. These muscles play a vital role in the movement of the chest during breathing. They also help to solidify the thoracic region and protect the lungs.
Mammalian lungs are located in the thoracic cavity where they are surrounded and protected by the rib cage, intercostal muscles, and bound by the chest wall. The bottom of the lungs is contained by the diaphragm, a skeletal muscle that facilitates breathing.Breathing requires the coordination of the lungs, the chest wall, and most importantly, the diaphragm.o increase the volume of the lungs, the chest wall expands. This results from the contraction of the intercostal muscles, the muscles that are connected to the rib cage. Lung volume expands because the diaphragm contracts and the intercostals muscles contract, thus expanding the thoracic cavity.
