Three-dimensional visualisation based on segmented human data of the joints of the head and neck. The seven cervical vertebrae, the smallest and lightest vertebrae, support the head and neck and allow the skull to turn and nod. Nodding occurs when an individual flexes and extends the neck. Flexion, a bending movement, occurs when the angle between the articulating cervical bones decreases and extension occurs when the angle between the cervical bones increases.
