About
The character 蠕 is a phono-semantic compound. The radical 虫 on the left indicates its semantic category of insects, worms, or crawling creatures. The phonetic component 需 on the right provides its pronunciation. Its core meaning describes the slow, rhythmic wriggling motion of soft-bodied invertebrates like worms or caterpillars. In modern biological and medical contexts, this concept has expanded to describe similar wave-like muscular contractions, such as peristalsis in the digestive tract, applying the idea of worm-like movement to involuntary physiological processes.
