Anatomy

The head muscle’s sister linking thoracic vertebrae to the lower cervical spine — narrower and slightly deeper; the posterior scapular vessels cross it on their way to levator scapulae.

Origin & insertion

Spinous processes of T3–T6.

Action

Rotates the neck to its own side and extends it; bilateral contraction extends the cervical spine.

Innervation

Posterior rami of the lower cervical nerves.

Clinical notes

Its referred pain above the ear and around the eye mimics cervicogenic headache; palpated as a deep tender knot below splenius capitis.
