Siriam Navigator

Begin with anatomy.

Choose a structure and follow it through the platform: knowledge, research, protocols and the formulations mapped to it.

Dermatomes

Segmental cutaneous territories, from the suboccipital transition field to the innermost perianal ring.

Cervical

C0Suboccipital transition field between cranium and atlas.→C1Largely without a distinct cutaneous strip; described as a transition field.→C2Posterior scalp to the vertex and the angle of the mandible.→C3Posterolateral neck and lower occipital surface.→C4Supraclavicular field across the shoulder line.→C5Lateral shoulder cap and lateral upper arm.→C6Lateral forearm to the thumb.→C7Middle finger and central posterior forearm.→C8Medial forearm and little finger.→

Thoracic

T1Medial upper arm and axillary border.→T2Upper thoracic band across the axilla and upper chest.→T3Thoracic band at the level of the third rib.→T4Band at the nipple line.→T5Mid-thoracic band between nipple line and xiphoid.→T6Band at the level of the xiphoid process.→T7Lower thoracic band beneath the costal margin.→T8Band between costal margin and upper abdomen.→T9Upper abdominal band.→T10Band at the umbilical line.→T11Band below the umbilicus.→T12Suprainguinal band across the lower abdominal wall.→

Lumbar

L1Inguinal line and upper anterior thigh.→L2Anterior mid-thigh.→L3Anterior distal thigh toward the medial knee.→L4Medial leg and medial malleolus.→L5Lateral leg and dorsum of the foot.→

Sacral

S1Lateral foot border and posterior calf.→S2Posterior thigh strip and posterior calf.→S3Medial gluteal fold and ischial field.→S4Perianal and lower sacral surface.→S5Innermost perianal ring.→

The Navigator is an educational reference interface. It describes anatomical organisation and where formulations are intended to be applied. It is not a diagnostic tool and makes no therapeutic claims.
