Caption: Light micrograph of the tip of a stinging hair of a nettle leaf, Urtica dioica. The stinging hairs have silicified tips which break off, as the glass of an ampoule, when the nettle is brushed against or stroked (not grasped). The sting penetrates the skin, injecting a mixture of acetylcholine and histamine; the former is a neurotransmitter substance normally produced at nerve terminals, the latter a chemical mediator normally produced by mast cells and responsible for many of the symptoms of allergic reactions. Magnification unknown. (See M625/364 for comparison with the tip of a glass ampoule)
