/Which muscle helps us to rotate the head?
The skeletal muscles are split into groups axial (trunk and head muscles) and appendicular (arms and leg muscles). The axial muscles are classified according to position, function, or both. Most axial muscles can appear to overlap the frontiers as they move over to the appendicular portion of the skeleton.
Answer and Explanation:
Attached to the top of the vertebral column, the head is supported, pushed and rotated by the muscles in the neck. The head rotates when those muscles function unilaterally. The head flexes or extends as they contract bilaterally. The sternocleidomastoid is the main muscle that flexes and rotates the head laterally. Additionally, the flexors of the head are all muscles working together.
