Dermatomes is a handy reference map of which spinal nerve roots relay sensation from particular areas of the skin along with a cutaneous nerve distribution.

Dermatomes provides a zoomable map of anterior and posterior dermatomes and cutaneous nerve distributions with a reference chart of important landmarks . Pinch to zoom in and out on the map.

Dermatomes is an essential reference for neurologists, emergency physicians, family doctors, medical students, physiotherapists, chiropractors, osteopaths and other medical professionals – or anyone curious about neuroanatomy and the workings of the human body.

Featured in Apple's 2010 essential apps for medical students.

Consult a doctor if you are experiencing neurological symptoms. This app should not be relied upon to make clinical decisions, which remain the full responsibility of the user. Dermatomes are variable between individuals and the pattern of sensory loss is usually less than the entire dermatome, because of overlap. The map and landmarks presented are a consensus view drawn from numerous sources.

Dermatomes comes with lifetime email support.

Don’t bother. You can get better Dermatomes maps on the internet

A few mistakes, but overall very nice.


Please double check a few regions:

anterior genitofemoral region: my notes depict a dermatome level of S2, not S3.
posterior plantar surface should be split as follows: digit 1 should be L4, digit 2-4 should be L5, and digit 5 should be S1

These mistakes correspond to what I have studied in Chiropractic school. I have only double checked the lower extremities, but other than these mistakes, this is a very handy and useful app to show patients, and quickly reference dermatomes

Developer Response ,

Thanks for the review Jonathan, glad you find the app useful.

Dermatomes vary between individuals resulting in differences between even the most authoritative sources. The values presented in the Dermatomes app are representative of the best consensus between available sources but users should be aware that every individual is unique and there will be some variation.
