A paper cut triggers a remarkably coordinated repair response. Blood vessels constrict, platelets form a clot, inflammatory cells clear microbes and debris, and growth factors stimulate collagen deposition and re-epithelialization. Despite being tiny, paper cuts often hurt more because they expose a high density of pain receptors in the fingertips. 🩸🩹🧬
