The brain is protected by:
- A. the meninges.
- B. a cushion of fluid.
- C. the bony skull.
- D. All of the above.
Correct Answer: D
Rationale: The brain is protected by multiple layers of defense, including the meninges (protective membranes), cerebrospinal fluid (a cushioning fluid), and the bony skull. The meninges consist of three layersâ€â€dura mater, arachnoid mater, and pia materâ€â€that provide structural support and protection. Cerebrospinal fluid surrounds the brain and spinal cord, acting as a shock absorber. The skull provides a rigid barrier against physical injury. Together, these structures safeguard the brain from damage.

Which of the following is the causative agent of East African trypanosomiasis?
- A. Trypanosoma cruzi
- B. Trypanosoma vivax
- C. Trypanosoma brucei rhodanese
- D. Trypanosoma brucei gambiense
Correct Answer: C
Rationale: The correct answer is C: Trypanosoma brucei rhodanese. East African trypanosomiasis is caused by Trypanosoma brucei, specifically the subspecies Trypanosoma brucei rhodanese. This parasite is transmitted by tsetse flies and infects humans, causing sleeping sickness. Trypanosoma cruzi (Choice A) causes Chagas disease, not East African trypanosomiasis. Trypanosoma vivax (Choice B) causes a different form of animal trypanosomiasis. Trypanosoma brucei gambiense (Choice D) is responsible for West African trypanosomiasis, not the East African form. Therefore, the correct choice is C.
