Cervical Vertebrae - Movements of The Cervical Spine

Movements of The Cervical Spine

The movement of nodding the head takes place predominantly through flexion and extension at the joint between the atlas and the occipital bone, the atlanto-occipital joint. However, the cervical spine is comparatively mobile, and some component of this movement is due to flexion and extension of the vertebral column itself.

The movement of shaking or rotating the head left and right happens almost entirely at the joint between the atlas and the axis, the atlanto-axial joint. A small amount of rotation of the vertebral column itself contributes to the movement.

    The movements of the eyes express the perpetual and unconscious courtesy of the parties.

    He sways his head from side to side, with movements like a snake;
    And when you think he’s half asleep, he’s always wide awake.
    —T.S. (Thomas Stearns)

    Much of a man’s character will be found betokened in his backbone. I would rather feel your spine than your skull, whoever you are. A thin joist of a spine never yet upheld a full and noble soul.
    Herman Melville (1819–1891)
