Posted on 03 Mar 2012 22:22. The scalene muscles are three paired muscles of the neck, located in the front on either side of the throat, just lateral to the sternocleidomastoid. There is an anterior scalene (scalenus anterior), a medial scalene (scalenus medius), and a posterior scalene (scalenus posterior).They derive their name from the Greek word skalenos and the later Latin scalenus meaning uneven, similar to the scalene triangle in mathematics, which has all sides of unequal length.he insertion of the scalene anterior and medius may be close together on the first rib, making the space narrower. There may be fibrous bands between the two muscles which act like a sling which elevates the artery and the brachial plexus. The presence of a scalenus minimus in the area can add to the problem.
