All cervical vertebrae rotates
There is rotation of head around the dens of the axis. Dens is actually derived from the body of the atlas vertebra.
Your head can move forward, backward, side to side, and rotate along a vertical axis. It has a wide range of motion to allow you to look in various directions and orientations.
Rotate the head from one side to another.
Sauropods' necks were not as flexible as they are usually portrayed in television. Sauropods could move their neck and head from side to side or somewhat up and down, but they definitely couldn't rotate their head around or turn their neck into a U-shape in order to look over their shoulder.
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.
Rotation
Lift your chin and look up for a count of 5, then lower head to original position. Tilt head toward shoulder on one side for a count of 5 then to the other side for a count of 5. Rotate head from side to side without straining 5 times for each side. Place hands behind head and push head back against them 5 times. Place hand on forehead and push against them 5 times. Do each set 3 times.
The function of the Sternocleidomastoid is to flex the neck forward and to rotate the head toward sholder on the opposite side..
Rotation
yes, vertebrae can rotate such as turning to look to your side. They can also curve as in bending down to pick something up.
The atlantoaxial joint is responsible for allowing the head to rotate from side to side, enabling movements such as shaking the head no. It is formed by the first and second cervical vertebrae (C1 and C2) and is essential for flexibility and mobility of the head and neck.
The movement of turning the head from side to side is called rotation. This movement occurs at the joint between the first two cervical vertebrae, known as the atlas and axis. Rotation of the head allows for increased range of vision and flexibility in everyday movements.
