What Is Sternocleidomastoid muscle (SCM)?Sternocleidomastoid muscle also known as musculus sternocleidomastoideus or simply SCM is one of the largest, strongest and the most complex muscles in the neck because of its intricate connections to other parts of the body and its ability to do multiple actions. Although it sits innocently in the front neck and can be easily seen, felt and touched (externally), many of us are unaware of its presence. This is because SCM is quite strong, it rarely hurts or gets damaged. However, if used improperly, it can create a tremendous amount of trouble in the form of facial pain, headaches, jaw pain and tension, blurry vision, dizziness, and hearing disturbance.
(SCM) FunctionThe SCM is responsible for several important functions, such as:
- side to side rotation of the head/neck
- tilt (left or right) movement of the head/neck
- bending movement of the head/neck
- stabilising the head/neck
- support in chewing and swallowing
