•  oncosphere
•  cysticerus larva
•  Miracardium

Solution
The six-hooked embryo of Taenia solium is called hexacanth. Hexacanth along with all its membranes is called oncosphere. The oncospheres are passed out along with human stools, which is eaten up by the pig (secondary or intermediate host). Thus, oncospheres reach in the intestines of pigs and infect them.
