Splenius cervicis inserts on which structures?

Explanation:
Splenius cervicis attaches to the transverse processes of the upper cervical vertebrae, typically C1 to C3 (some sources include C4). This insertion location lets the muscle extend, rotate, and laterally flex the neck when it contracts. The mastoid process and occipital bone are the insertion sites for the splenius capitis, not cervicis, and the zygomatic arch has no role here. So the transverse processes of the upper cervical vertebrae are where splenius cervicis inserts.
