Feelings of numbness, tingling, or sensory loss are very common complaints, especially with various neuropathies. Neuropathies are disorders that affect the peripheral nerves, which are the nerves that carry signals from the brain and spinal cord to the rest of the body. Knowledge of the cutaneous sensory supply of individual peripheral nerves and nerve roots is essential for diagnosing and treating neuropathies. Cutaneous sensory supply refers to the area of skin that is innervated by a specific nerve or nerve root. For example, the median nerve supplies sensation to the thumb, index finger, middle finger, and half of the ring finger. If there is damage to the median nerve, the patient may experience numbness or tingling in these areas. By knowing the cutaneous sensory supply of each nerve and nerve root, doctors can identify which nerve is affected and provide appropriate treatment.

麻木、刺痛或感觉丧失的感觉是非常常见的主诉，尤其是对于各种神经病。神经病是影响外周神经的疾病，外周神经是将信号从大脑和脊髓传递到身体其他部分的神经。单个周围神经和神经根的皮肤感觉供应的知识对于诊断和治疗神经病是必不可少的。皮肤感觉供应指的是受特定神经或神经根支配的皮肤区域。例如，正中神经为拇指、食指、中指和半个无名指提供感觉。如果正中神经受损，患者可能会在这些区域感到麻木或刺痛。通过了解每条神经和神经根的皮肤感觉供应，医生可以确定哪条神经受到影响，并提供适当的治疗。
