The sternocleidomastoid muscle primarily rotates the head to the opposite side. When one side of the sternocleidomastoid contracts, it causes rotation of the head towards the opposite side while also tilting it to the same side. However, if both sides contract together, they flex the neck forward. Thus, the muscle does not rotate the head to the same side; that action is performed by other muscles.

What is the function of the sternocleidomastiod?
The function of the Sternocleidomastoid is to flex the neck forward and to rotate the head toward sholder on the opposite side..
What are the functions of the sternocleidomastoid?
These two muscles of the neck flex and rotate the head.
What Muscle aids in rotation of axis and atlas?
The sternocleidomastoid pair and the splenius capitus pair act to rotate the head around the joint between the axis and the atlas.The sternocleidomastoid pair and the splenius capitus pair act to rotate the head around the joint between the axis and the atlas.
Prime mover of flexion of head?
The prime mover of flexion of the head is the sternocleidomastoid muscle. It acts to tilt and rotate the head to the opposite side when contracted unilaterally and both muscles together flex the neck and bring the head towards the chest.
Is the sternocleidomastoid an adductor?
No, the sternocleidomastoid is not an adductor. It is a muscle in the neck that primarily functions to rotate and flex the head. Its actions include turning the head to one side and bending the neck forward, rather than moving limbs toward the midline of the body, which is the role of adductor muscles.
What is the muscle on the side of the neck that flexes the head?
sternocleidomastoid
Do rats have a sternocleidomastoid?
I believe so. the sternocleidomastoid serve to turn the head from side to side and to able one to nod; since I have seen a rat turn from side to side and look up and down I would believe this to be true.
Does the sternomastoid muscle muscle control head movement?
The stenrocleidomastoid muscle bilaterally does neck extension, while unilaterally, they laterally flex the Neck to the same side of the muscle contracting, and rotates th neck to the contra lateral side. So if you rotate to the left, the right sternocleidomastoid muscle is working. The right stenrocleidomastoid will also cause right lateral flexion( side bending)
What is the function of the sternocleidomastiod muscle?
The sternocleidomastoid muscle, also known as sternomastoid and comonly abbreviated as SCM, is a paired muscle in the superficial layers of the anterior portion of the neck. It acts to flex and rotate the head.
What is the sternocephalicus muscle?
The sternocephalicus is a part of the sternocleidomastoid muscle, which "passes obliquely across the side of the neck, being enclosed between the two layers of deep cervical fascia." The origin of its name, sternocleidomastoid, stems from the fact that it has two heads, extending from the sternum and the clavicle.The sternocleidomastoid has three major actions; the first is to bring the head to the shoulder. The second is to rotate the head and the third is to assist in "elevating the thorax during forced inspiration."[The quotes are from the 1977 Collector's Edition of Henry Gray's Gray's Anatomy.]
Why does the moon not rotate as does the earth?
The moon does rotate on its axis as the earth does. The earth rotates once in a day and the moon rotates once in a month ( for those who want to quibble, it's a little more than 27 days ). ADD---the moon rotate at the same speed of the earth, that why we always see the same side of the moon which give the impresion that the moon doesnt rotate but it does!
What side of the moon do you see from earth?
You always see the same side - as the moon takes the same time to orbit the earth as it does to rotate once on its axis !
