The Semispinalis Cervicis is a muscle located in the neck region, part of the deeper layer of the back muscles. It originates from the transverse processes of the upper thoracic vertebrae and inserts into the spinous processes of the cervical vertebrae. This muscle plays a crucial role in extending and rotating the neck. Functionally, the Semispinalis Cervicis helps stabilize the cervical spine and contributes to posture. It works in conjunction with other muscles in the semispinalis group, such as the Semispinalis Capitis, to facilitate head movements and maintain balance during various activities.
