ATTACHMENTS:
- The splenius cervicis attaches from the spinous processes of T3−T6 to the posterior tubercles of the transverse processes of C1-C3.
ACTIONS:
- The splenius cervicis extends, laterally flexes, and ipsilaterally rotates the neck at the spinal joints.
NOTE: Where they overlap, the splenius cervicis is deep to the splenius capitis from the posterior perspective.
