Anatomical terms of muscle[edit on Wikidata]

The splenius cervicis (/ˈspliːniəs sərˈvaɪsɪs/) (also known as the splenius colli, /- ˈkɒlaɪ/) is a muscle in the back of the neck. It arises by a narrow tendinous band from the spinous processes of the third to the sixth thoracic vertebrae; it is inserted, by tendinous fasciculi, into the posterior tubercles of the transverse processes of the upper two or three cervical vertebrae.

Its name is based on the Greek word σπληνίον, splenion (meaning a bandage) and the Latin word cervix (meaning a neck). The word collum also refers to the neck in Latin.

The function of the splenius cervicis muscle is extension of the cervical spine, rotation to the ipsilateral side and lateral flexion to the ipsilateral side.
