Correct Answer: D

Rationale: Huntington disease is a genetic disorder that leads to the progressive degeneration of neurons in the brain, resulting in motor, cognitive, and psychiatric symptoms. Multiple sclerosis is an autoimmune disease, polio is caused by a virus, and encephalitis is inflammation of the brain. Huntington disease highlights the impact of genetic mutations on neuronal health.

Correct Answer: C

Rationale: Baroreception is the correct answer because it is a sensory input related to monitoring blood pressure, which is part of the autonomic nervous system. Vision, taste, and proprioception are sensory inputs that are part of both the somatic and autonomic systems. Vision and taste involve sensory information processed by both systems, while proprioception provides information about body position and movement, which is essential for both systems to coordinate responses.

Correct Answer: B

Rationale: The correct answer is B: sympathomimetic drug. Sympathomimetic drugs stimulate the sympathetic nervous system, leading to bronchodilation and opening of airways wider, which is beneficial in treating asthma. A: Sympatholytic drugs inhibit the sympathetic nervous system and would not be effective in widening airways in asthma treatment. C: Anticholinergic drugs block the action of acetylcholine, which can cause bronchoconstriction and are not used to widen airways in asthma. D: Parasympathomimetic drugs stimulate the parasympathetic nervous system, leading to bronchoconstriction and are not used to treat asthma by opening airways wider.

Correct Answer: D

Rationale: The correct answer is D: chicken. Chickens are not typical reservoirs for rabies as they are not known to carry the rabies virus. Dogs, bats, and skunks can serve as reservoirs for rabies due to their susceptibility to the virus. Dogs are a common source of rabies transmission to humans, while bats and skunks are known carriers of the virus. Therefore, the correct answer is D as chickens do not play a role in the spread of rabies.
