A larval form of certain tapeworms that looks like a cysticercus, but has a fully developed head inside the cyst.
The cysticercoid stage of the tapeworm is crucial for its development in the host.
Cysticercoid is formed from "cystis" (from Greek "kystis", meaning bladder or sac) and "-cercoid" (from Greek "kerkos", meaning tail). The term describes a larval form of certain tapeworms that resembles a small sac with a tail.
Think of a 'sac' ('cystis') that has a 'tail' ('kerkos') — this helps you remember that a cysticercoid is a larval form of a tapeworm that looks like a small sac with a tail.
