Your 1st vertebra is shaped like a ring (atlas) and 2nd verebra is shaped like a peg at it's front (axis) forming a a pivot joint so your neck can rotate side to side
The full range of rotation for the neck is approximately 90 degrees to each side, totaling 180 degrees from side to side. This allows for movement to the right and left, as well as the ability to turn the head to look behind.
The axis is the second cervical vertebra (C2) in the neck region, which forms a joint with the first cervical vertebra (C1) called the atlantoaxial joint. This joint allows for rotation of the head from side to side, giving us a wider range of movement in the neck.
The rotation of the head is called "head rotation" or "cervical rotation." This movement allows the head to turn from side to side.
Rotation
When the head is moved from side to side, the first vertebra pivots around the second vertebra called the axis. This movement allows for rotation and flexibility of the neck.
Rotation
On my fan their is a little switch on the side if the neck of the fan
When the head is moved from side to side, the first vertebra (atlas) pivots around the dens (odontoid process) of the second vertebra (axis). This motion allows for the rotation and flexibility of the neck.
I believe the answer is head and neck. Hope this helps! :)
Individually rotation of the head to the opposite side. Together , flexion of the neck.
The movement is called rotation, where the head pivots around the axis of the neck to enable movement from side to side. This movement primarily involves the atlas and axis vertebrae at the top of the spine.
It's called the pivot joint. It allows your head to move from side to side.
