Functional EMG Mapping.

A bilateral, segment-by-segment representation of the spinal column from C0 to S5, built as a teaching model for professional education.

Educational visualisation intended for research and professional education. This is not diagnostic software, it does not display patient data, and the values shown are illustrative demonstration values only.

Each spinal nerve divides into a ventral and a dorsal ramus. The medial branch of the dorsal ramus runs immediately lateral to the spinous process, supplying the deep paraspinal musculature and a narrow overlying strip of skin. Because that arrangement repeats at every level and on both sides, the paraspinal column can be read as a regular bilateral grid.

The model below expresses that grid as a colour-coded bilateral heatmap. Select any metamer to open its anatomical overview, peripheral nerve, dermatome, associated musculature, neurocutaneous region and the SIRIAM formulations mapped to that segment.

Professional mode

Segmental links are protected.

Metameric cross-references are reserved for practitioners trained in segmental reasoning. Enter your professional code to continue.

Reading the model

Bilateral

Left and right are rendered separately at every level, because the paraspinal column is naturally paired.

Segmental

Rows follow the metameric sequence C0 → S5 without interpolation between levels.

Illustrative

Intensities are fixed demonstration values that illustrate the representation, not measurements.
