Answer 2

Hey dear,

● Serratus anterior -
- Originates from first 8-9 ribs.
- Inserts on scapula.
- Usually, it causes upward rotation and abduction of scapula.

# In respiratory distress -
- In respiratory distress, scapula is stabilized and origin & insertion of serratus anterior is switched.
- In this case, it pulls the ribs upwards to allow more air into the lungs.

Thanks for asking...
