Anatomical terms of muscle |
The posterior scalene, also known as the scalenus posterior, the smallest and most deeply seated of the three scalene muscles, arises, by two or three separate tendons, from the posterior tubercles of the transverse processes of the lower two or three cervical vertebrae, and is inserted by a thin tendon into the outer surface of the second rib, behind the attachment of the anterior scalene.
It is occasionally blended with the middle scalene.
