Splenius Capitus and Cervicis Muscles: Location, Actions, and Trigger Points

Cervicus derives from the Latin word cervix which pertains to the neck, referring to the splenius cervicus having its origin on the cervical spine.

Trapezius Muscle: Location, Actions, and Trigger Points

The trapezius is a three part (tripartite) muscle of the upper back extending from the base of the skull all the way to the lower thoracic spine and laterally from the clavicle to the entire length of the spine of the scapula. Together the two trapezii form a diamond or kite-shaped trapezoid from which the muscle derives its name.

Levator Scapulae Muscle: Location, Actions, and Trigger Points

The levator scapulae is a muscle located on each side of the neck, situated posteriorly1.

Always in the shadow of the large sternocleidomastoid and hardly ever getting a moments rest.

Along with the trapezius, the levator scapulae works to shrug the shoulders by its raising of the medial margin of the scapula. If the scapula are fixed the muscles assist in cervical extension and if used alone flex the neck laterally to one side.

The sternocleidomastoid (SCM) is a muscle of the neck so-named because it originates on the sternum (sterno) and the clavicle (cleido) and inserts on the mastoid process1 (mastoid) which is an easily located bony prominence behind the ear. The muscles pass diagonally across the front and side of the neck beginning at the top of the sternum and ending behind the ear. This two sided muscle is large and ropy, making it the most prominent muscle visible at the front of the neck.
