When the Scalenes act from above, they elevate the first and second ribs.
 
Acting from below, they produce side flexion of the vertebral column<ref>Buford JA, Yoder SM, Heiss DG, Chidley JV (Oct 2002).

== Function  ==
 
When acting from above, they help to elevate the 1st rib and are accessory muscles of respiration.
 
Acting from below they are cervical flexors and rotators.
