Where does the splenius cervicis originate and insert?
Splenius capitis muscle
Origin | Spinous processes of vertebrae C7-T3, nuchal ligament |
---|---|
Insertion | Lateral superior nuchal line of occipital bone, mastoid process of temporal bone |
Action | Bilateral contraction: Extends head/neck Unilateral contraction: Lateral flexion and rotation of head (ipsilateral) |

What is the definition of cervical?

In the cervical spine, eight nerve roots branch out that primarily control the function of your shoulders, arms and hands.
