Overview
Semispinalis cervicis fits between the deeper multifidi and the more superficial erectors and serratus anterior. It is a thin muscle that connects the transverse processes of the upper thoracic vertebrae with the mid-cervical vertebrae. Consequently, It is in a position to trap and compress the lower cervical vertebrae. Interestingly, the posterior rami of those lower cervical vertebra also innervate it.
Origin
- transverse processes of T1-T5 or T6
Insertion
- spinous processes of C2-C5
Function
- extension,
- lateral flexion
- some rotation of the lower cervicals
Innervation
- posterior rami of local vertebrae

Semispinalis Muscle Group
The semispinalis muscle group includes:
Capitis attaches to the cranium base, but the other two are interspinous muscles. These muscles are deep to the extrinsic back muscles and superficial to other interspinous muscles. They provide another layer of paraspinal erectors to support the cervical muscles on the thoracic column.
Often, these muscles are considered to be another, deeper layer of the erector spinae. Comparatively, they have similar attachments and perform a similar function to the erectors just superficial to them. Likewise, they are a longer version of the multifidi muscles, which are deep to this semispinalis group.
All of the semispinalis muscles have statistically significant variations in their structure.
