Systematic Map of Nerve Distribution Across the Male Skin

Description

Presented as a full-body 3D male figure in anatomical position, this surface map partitions the skin into color-coded cutaneous territories consistent with segmental and peripheral nerve distribution across the trunk and limbs. Anterior regions of the thorax and abdomen align with intercostal and subcostal cutaneous branches, while the upper limb fields correspond to brachial plexus derivatives such as the intercostobrachial nerve (T2), medial cutaneous nerve of arm and forearm, and the radial, median, and ulnar nerve territories distally. Over the pelvis and lower limb, the pattern logically follows lumbar and sacral contributions including iliohypogastric and ilioinguinal areas, lateral femoral cutaneous territory laterally on the thigh, and femoral, obturator, sciatic, tibial, and common fibular distributions toward the leg and foot. Color boundaries emphasize where adjacent dermatomes and named cutaneous nerves overlap. Clean landmarks. Cutaneous mapping matters most when symptoms do not respect a single joint or muscle group. This layout supports bedside localization of radiculopathy versus mononeuropathy, for example differentiating an L5 distribution from superficial fibular nerve sensory loss on the dorsum of the foot, or separating C6 radicular pain from median nerve compression in carpal tunnel syndrome. It also reflects the clinical reality that axillary or thoracic procedures can alter sensation, with classic teaching examples including intercostobrachial nerve involvement after axillary lymph node dissection or mastectomy. Use this asset in gross anatomy and neuroanatomy teaching to introduce dermatomes, peripheral nerve territories, and the logic of segmental innervation on the body surface. It also fits neurology, pain medicine, and rehabilitation publications where a clean, whole-body reference helps document sensory exam findings or patient-reported dysesthesia patterns.
