The intercostal muscles are a group of intrinsic chest wall muscles that run between the ribs and are involved in the movements of the rib cage.
They consist of three principal layers:
- External intercostal muscles
- Internal intercostal muscles
- Innermost intercostal muscles
They are all supplied by the intercostal nerves, arteries and veins. The fibers of the external and internal intercostal muscles run in opposite directions, giving them different functions, as well. Due to their origins and insertions, the external intercostal muscles aid in forced inspiration, whereas the internal intercostal muscles contribute to the forced expiration.
In this video we go over the anatomical features including the origins, insertions, innervation and functions of these muscles in order to help you understand how they are arranged and work together in the human thorax.
- 0:14 introduction
- 0:25 origin and insertion of the external intercostal muscles
- 0:41 origin and insertion of the internal intercostal muscles
- 0:51 origin and insertion of the innermost intercostal muscles
- 1:07 intercostal nerves, veins and arteries supply
- 1:30 functions of the intercostal muscles
