Yes.
external/ internal intercostals
The internal intercostal depresses the ribcage while the external intercostals elevate the ribcage
Muscles of inspiration include: diaphragm, scalenes, pectoralis minor, and external intercostals. The muscles of expiration include: abdominals and internal intercostals.
intercostals..internal and external
Im not expert, but isn't it the diaphragm and rib muscles, the muscles between the ribs, internal and external intercostals.
External intercostal muscles are the ones between the ribs that help elevate them during inspiration.
external and internal intercostals
the sternoclediomastoid, scalenes and external intercostals all work to increase throracic volume. hope that helps
The muscles of the thoracic wall consist of the intercostals and the diagram. The intercostals have several layers: external intercostal, internal intercostal and innermost intercostals. These are the same in cats and humans.
external intercostals and the diaphragm
The diaphragm is the prime mover of inspiration. It flattens on contraction, increasing the vertical dimensions of the thorax, which draws air into the lungs. The external intercostals also contribute to inspiration. The internal intercostals and rectus abdominis are expiratory muscles.
The intercostal muscles are located between the ribs. They play important roles in breathing. There are two sets of intercostal muscles, external and internal. The external intercostals contract during normal inspiration, causing the rib cage to expand out and up and thus increase the volume of the chest cavity. The internal intercostals are used during forced expiration only. When they contract, the rib cage pulled down and together, shrinking the volume of the chest cavity.
