Anatomical Attachments:

• Origin: Attaches to the transverse processes of T1 through T5 vertebrae.

Synergist: Semispinalis capitis and cervicis, Splenius capitis and cervicis, Spinalis cervicis, Interspinales, Iliocostalis cervicis, Multifidus.

Antagonist: Sternocleidomastoid, Longus colli and capitis, Scalenus anterior, medius, and posterior.
