Splenius

Splenius is a broad, straplike muscle in the back of the neck. It pulls on the base of the skull from the vertebrae in the neck and upper thorax. It is involved in movements such as shaking the head.

Anatomy

The splenius muscle is made up of two parts: the splenius capitis and the splenius cervicis. The splenius capitis is located in the back of the neck, attaching to the skull. The splenius cervicis is located more inferiorly and attaches to the cervical vertebrae.

Function

The splenius muscles are involved in movements of the head and neck. Contraction of the splenius capitis causes the head to rotate and extend. The splenius cervicis contributes to neck extension and lateral flexion.

Clinical significance

Injury or strain to the splenius muscles can cause pain and restriction in movement. This can occur as a result of poor posture, overuse, or trauma. Treatment typically involves physical therapy and pain management.
