The cervical spine consists of seven vertebrae, C1 to C7, which support the skull, enable diverse head movements, and protect the spinal cord. Its unique structure, including the atlas and axis, facilitates rotation and flexion, making it crucial for both stability and mobility of the neck.

Cervical Spine Anatomy

The cervical spine is the uppermost section of the vertebral column, consisting of seven vertebrae (C1-C7), which provide support and mobility to the head and neck. It plays a crucial role in protecting the spinal cord and facilitating a wide range of motion while maintaining stability and alignment of the head.

The atlas and axis are the first two cervical vertebrae of the spine, crucial for supporting the skull and enabling a wide range of head movements. The atlas (C1) allows nodding motions, while the axis (C2) provides the pivot needed for head rotation, thanks to its unique odontoid process or dens.
