Neck MusclesSome neck muscles have previously been discussed. Aside from the Scalene Muscle Group and the Suboccipitals Muscle Group, there are 3 other important muscles you should know about. They include Platysma, Longus Capitus, and Longus colli. Below is the study aid for massage therapy students.
PlatysmaOrigins are superficial fascia of deltoids and superficial fascia of pectoralis major.Insertions are muscles around angle of mouth and superficial fascia of the lower face. Actions--depresses mandible (lower jaw), pulls corners of mouth down, and makes the skin of the anterior neck tense. Since Platysma allows you to pout,it is called the pouting muscle and is the most superficial muscle of the front neck.
Longus CapitisOrigin is transverse processes of C3-C6.Insertion is inferior base of occipital bone. Actions--flexes neck and rotates head.
Longus ColliOrigins are vertebral bodies of C5-T3, bodies of T1-T3, and anterior transverse processes of C3-C5.Insertions are anterior tubercle of C1, anterior transverse processes C5-C6, and vertebral bodies C2-C4. Actions--flexes and laterally flexes neck, and rotates head. This muscle actually contains 3 muscles: Longus Colli Superior Oblique Longus Colli Inferior Oblique Longus Colli Vertical
