The splenius cervicis (/ˈspliːni.əs sərˈvaɪs[invalid input: 'ɨ']s/) (also known as the splenius colli, /ˈspliːni.əs 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).[1] The word collum also refers to the neck in Latin.[1]
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.[2]
