This guide introduces five regions and some possible concerns. It is educational and does not diagnose symptoms or recommend a particular treatment. The main model combines reference anatomy with scroll-driven educational overlays, not a patient scan. Not every spinal condition is covered here.
01 / C1 — C7
Changes in a cervical disc or nearby joints can sometimes irritate a nerve root. Symptoms may travel from the neck into the shoulder or arm, with tingling, numbness, or weakness. Similar symptoms can have other causes, and some imaging changes cause no symptoms.
The ivory structures are vertebrae; the blue layer is an intervertebral disc. In a disc herniation, disc material can extend beyond its usual boundary and may irritate a nearby nerve root. This image is illustrative, not a diagnosis.
02 / T1 — T12
Upper-back discomfort can involve muscles and other tissues. The thoracic spine naturally curves outward; excessive rounding is called hyperkyphosis. A visible curve does not, by itself, explain someone’s symptoms or determine their treatment.
A gentle thoracic curve is normal. Excessive curvature has several possible causes and needs individual assessment. The 3D story illustrates an exaggerated curve with a smooth, bounded deformation. It does not represent a measured clinical angle or a diagnosed abnormality.
03 / L1 — L5
Low-back pain can come from several structures. A herniated disc may irritate a nerve; spinal stenosis describes narrowing of spaces around nerves. Either can be associated with leg symptoms. Sciatica describes a pattern of symptoms, not one single cause.
A disc sits between adjacent vertebral bodies. A herniation and narrowing around nerves are different conditions. This close-up introduces the anatomy; the illustration cannot identify the cause of a person’s pain.
04 / SACRUM · PELVIS
Sacroiliac joint problems can produce pain around the lower back or buttocks. Sacroiliitis means inflammation of one or both joints. Symptoms overlap with other conditions, so location alone is not enough to identify the source.
The paired SI joints sit between the sacrum and the left and right hip bones. The pelvis is shown with reduced opacity in the main model to make this relationship easier to see. A glow marks the area, not a confirmed injury.
05 / TAILBONE
Tailbone pain, also called coccydynia, can follow a fall or prolonged pressure. It may be worse while sitting or when standing up. Sometimes no clear cause is found; persistent or disruptive pain deserves assessment.
The coccyx is below the sacrum. This educational view highlights its location and nearby anatomy. Pain here does not automatically mean a fracture or a structural problem.

The model was extracted from the BodyParts3D 4.0 PART-OF polygon dataset. Modifications: selected anatomical structures, coordinate conversion and scale, display materials, welded normals, and region labels. A subtle artistic motion animates nearby vertebrae; it is not a simulation of individual biomechanics or treatment. The original combined sacrococcygeal surface is preserved; its terminal faces are assigned a separate educational coccyx region. These boundaries are presentation labels, not a clinical segmentation.
Five regional illustrations and the cervical close-up film were generated using Grok Imagine from direct renders of the reference model. They are illustrative and not clinically validated. The lumbar film uses a direct render of the source geometry because the generated version introduced extra details. The continuous landing story now uses procedural disc protrusions and separate nerve strands attached to the moving disc meshes. SI-joint and tailbone color overlays identify locations; they do not depict measured inflammation or injury severity. Thoracic curvature is schematic. These effects are not to scale and do not show treatment or healing. Grok Imagine also supplied visual references for the ivory, teal and amber lighting direction. Earlier generated stills and films are retained as assets but are no longer displayed as landing-page controls.
