In nematology, a sensory amphid located on the lateral surface of roundworms, used for detecting chemicals and environmental changes.
From Greek 'deirê' (neck) and Latin '-id' (indicating a small structure), referring to sensory organs in the neck region of nematodes.
Deirids are like the tiny chemical sensors on a microscopic worm's body—they help the roundworm detect food, danger, and mates in its microscopic world.
