The medical term for a nosebleed is epistaxis. This term specifically refers to bleeding from the nasal cavity and can occur for a variety of reasons, such as trauma, dry air, or underlying medical conditions. Understanding medical terminology is important for effective communication in healthcare settings; knowing the correct terms can enhance both patient assessment and treatment.

The other terms listed represent different medical conditions. The epiglottis is a structure in the throat that prevents food from entering the windpipe during swallowing. Hemorrhage refers to an escape of blood from a ruptured blood vessel, which is a broader term and can apply to various types of bleeding, not just from the nose. Cyanosis is a condition characterized by a bluish discoloration of the skin due to a lack of oxygen in the blood, which is unrelated to nosebleeds.
