What movement do the rhomboids produce?
Scapular retraction and some downward rotation.

trapezius. (these two maintain scapula position at rest)
What movement does the serratus produce?
Scapular protraction and upward rotation.
Paralysis of what muscles lead to pathalogical winging?
Rhomboids and/or serratus
What movement does the pec minor produce/?
Protraction, downward rotation, and depression.
