A Cervical Spine Model is an anatomical representation of the uppermost portion of the vertebral column, typically comprising seven cervical vertebrae (C1–C7). This model helps demonstrate the structure, function, and pathology of the neck and upper spinal region.

Key Features:

Includes Vertebrae C1 to C7:

• C1 (Atlas) and C2 (Axis) are highly detailed to show their unique structure and function:

  • Atlas (C1) supports the skull and allows nodding.

  • Axis (C2) has the odontoid process (dens), allowing rotation.

• C3–C7 show typical cervical vertebrae anatomy (small body, bifid spinous process).

Intervertebral Discs:

• Models often include soft or colored discs between vertebrae to show:

  • Shock absorption

  • Flexibility

  • Common pathologies (e.g. herniated disc)

Occipital Bone & Skull Base (Optional):

• Some models include the base of the skull, demonstrating articulation with C1.

Nerve Structures:

• Advanced models feature spinal nerves emerging from intervertebral foramina, useful for explaining:

  • Nerve compression

  • Cervical radiculopathy

  • Pain referral patterns

Flexibility:

• Models may be:

  • Fixed – for static display

  • Flexible – to demonstrate natural neck motion (rotation, flexion, extension)
