Sternocleidomastoid functions bilaterally to create neck flexion and unilaterally to create ipsilateral lateral flexion and contralateral rotation.
Likewise, people ask, what muscles cause neck extension?
Splenius capitis and splenius cervicis are a pair of superficial muscles in the back of the neck. Bilateral contraction of these muscles produces extension of the neck.
Similarly, which muscles allow you to bend your neck to the side? Located underneath the platysma on the sides of the neck are the sternocleidomastoid muscles. With one on each side of the neck, these help flex the neck and rotate the head upward and side to side.

Other neck movements include: rotating the neck from side to side.What muscles laterally flex the neck?
The scalenes and the sternocleidomastoid act together in several muscle actions, such as lateral neck flexion. The sternocleidomastoid and the anterior scalene act together in neck flexion.Which muscles laterally flex the neck?

Lateral rotation is a rotating movement away from the midline. This is in the opposite direction to the movements described above.What does lateral flexion mean?
Lateral flexion describes the active or passive bending movement of a body part in the lateral direction, that is to say sidewards.What are the neck exercises?
