<h3>what are the function of External intercostal muscles ?</h3>
Intercostal muscles are the group of muscles present between the ribs that create and move the chest wall.
The muscles have three layers such as external intercostal muscles, internal intercostal muscles, and the innermost intercostal muscles.
These muscles are supplied by intercostal nerves, intercostal veins, and intercostal arteries.
The external intercostal muscles are involved in forced and quiet inhalation.
