Answer for screen readers
The external intercostal muscles primarily assist in inhalation by elevating the rib cage.
More Information
The external intercostal muscles are angled in a way that allows them to efficiently elevate the ribs, increasing the space in the thoracic cavity and thus facilitating air intake.
Tips
A common mistake is confusing the function of external intercostals with internal intercostals, which assist in expiration rather than inhalation.
