“Epidermal nerve fibers are unencapsulated nerve endings that detect noxious stimuli to conduct pain. In addition, sensory neurons innervating the epidermis are involved in the itch induction。” https://www.nature.com/articles/s41598-019-44866-0
“表皮神經纖維是未包裹的神經末梢，可檢測有害刺激以傳導疼痛。此外，支配表皮的感覺神經元參與了瘙癢的誘導。”（google 機器翻譯）
