Neurological System Questions Questions
Question 1 of 5
A neurologist asks a patient to stick out the tongue. Which cranial nerve (CN) is being tested?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
What is a common neurotransmitter?
Correct Answer: D
Rationale: Acetylcholine, GABA, and serotonin are all common neurotransmitters. Acetylcholine is involved in muscle activation and memory, GABA is an inhibitory neurotransmitter that reduces neuronal excitability, and serotonin regulates mood, appetite, and sleep. The diversity of neurotransmitters allows for complex regulation of nervous system functions.
Question 3 of 5
Which of these physiological changes would not be considered part of the sympathetic fight-or-flight response?
Correct Answer: D
Rationale: The correct answer is D: increased stomach motility. In the sympathetic fight-or-flight response, the body prioritizes blood flow to essential organs and muscles, leading to decreased activity in non-essential functions like digestion (stomach motility). This is to conserve energy for immediate action. Increased heart rate, sweating, and dilated pupils are all part of the fight-or-flight response as they prepare the body for quick action and heightened awareness.
Question 4 of 5
What central fiber tract connects forebrain and brain stem structures with the hypothalamus?
Correct Answer: B
Rationale: The correct answer is B: medial forebrain bundle. This tract connects the forebrain and brain stem structures with the hypothalamus, playing a crucial role in regulating various physiological functions. It is involved in the control of emotions, reward pathways, and feeding behaviors. The other choices are incorrect because: A) cardiac accelerator nerve is involved in regulating heart rate, not connecting forebrain structures with the hypothalamus; C) dorsal longitudinal fasciculus is associated with eye movements and visual processing, not connecting forebrain with the hypothalamus; D) corticospinal tract is responsible for voluntary motor movements, not involved in connecting forebrain structures with the hypothalamus.
Question 5 of 5
Which of the following can NOT be prevented with a vaccine?
Correct Answer: D
Rationale: The correct answer is D: listeriosis. Listeriosis is caused by a bacterium and there is currently no vaccine available for it. Tetanus, pneumococcal meningitis, and meningococcal meningitis, on the other hand, are all preventable with vaccines. Tetanus is prevented by the DTaP vaccine, pneumococcal meningitis by the pneumococcal conjugate vaccine, and meningococcal meningitis by the meningococcal vaccine. Therefore, listeriosis is the only condition among the options that cannot be prevented with a vaccine.
