Full Scalene Muscles Description
[Continued from above] . . . the neck from below. (3) The scalenus posterior raises the second rib or bends and slightly rotates the neck. This muscle may be absent or may extend to the third rib. When the scalene muscles are fixed from above, they elevate the first and second ribs to become respiratory muscles for breathing. Acting from below, they bend the spinal column to the same side or, if muscles act on both sides, the spinal column is slightly flexed.
