Thesplenius cervicis (/ˈspliːniəssərˈvaɪsɪs/) (also known as thesplenius colli,/-ˈkɒlaɪ/) is a muscle in the back of the neck. It arises by a narrow tendinous band from thespinous processes of the third to the sixththoracic vertebrae; it is inserted, by tendinousfasciculi, into theposterior tubercles of thetransverse processes of the upper two or threecervical vertebrae.
Its name is based on the Greek word σπληνίον,splenion (meaning a bandage) and the Latin wordcervix (meaning a neck).[1] The wordcollum 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]
