MEDICINE IS FUN.
THE SCALENUS MUSCLE The scalenus muscle helps lift the ribcage, assisting in breathing. It also assists in some rotation of the neck and flexion of the upper spinal column. Whereas the longus colli and the longus capitis muscles course upward, the scalenus muscle courses downward. Muscles always shorten in the direction of their origin.
