Final answer:
The habitat of the cysticercus of Taenia solium is the brain.
Step-by-step explanation:
The habitat of the cysticercus of Taenia solium is the brain. When the larvae of T. solium form cysts in brain tissue, it is called neurocysticercosis. This condition affects millions of people worldwide and is the leading cause of adult onset epilepsy in the developing world. Humans usually contract neurocysticercosis by the ingestion of eggs via the fecal-oral route, not by consuming undercooked pork.
