Final answer:
Strongyloidiasis severity increases with corticosteroid use due to immunosuppression. Goose bumps are caused by the contraction of arrector pili muscles in response to the sympathetic nervous system. Neurocysticercosis is contracted by ingesting undercooked pork containing Taenia solium tapeworm cysts.
Step-by-step explanation:
Strongyloidiasis cases are more severe in patients using corticosteroids because these drugs suppress the immune system. A suppressed immune system cannot effectively fight off the Strongyloides stercoralis parasitic worms, leading to a more severe infection.
In response to sympathetic nervous system stimuli, the arrector pili muscle contracts, causing hair to stand on end, which is known as goose bumps. This reaction is a part of the body's "fight or flight" response.
Humans contract neurocysticercosis primarily by ingesting undercooked pork that contains cysts of the Taenia solium tapeworm. Consuming infected pork leads to the tapeworm's life cycle continuing inside the human body, causing various health issues.
