Neurology Exam Questions Questions
Question 1 of 5
A 26-year-old male presents with moderate 'tightening' bilateral headache. These headaches began approximately one week ago. He denies any sensitivity to light or sound, dizziness, fatigue, changes in memory and does not experience nausea or vomiting. Headache episodes last a few hours. He is stressed about a presentation he has to give to his company owners later this week. He remembers having occasional headaches with fatigue or stress dating back to his teenage years. There is no significant past medical history. Funduscopic evaluation is negative for papilledema, and there is pericranial muscle tenderness upon palpation. The remainder of his neurological examination is normal. Which of the following is most appropriate next step in diagnosis?
Correct Answer: D
Rationale: Bilateral, tightening headache with stress and muscle tenderness, without red flags (e.g., papilledema), suggests tension-type headache. Imaging is not indicated in the absence of neurological deficits or sinister features.
Question 2 of 5
The job of the Nervous System is:
Correct Answer: D
Rationale: The nervous system receives sensory input (via receptors), integrates it (in the brain/spinal cord), and triggers motor output (via effectors), encompassing all listed functions.
Question 3 of 5
Which of the following statements regarding the nervous system is true?
Correct Answer: B
Rationale: Motor neurons transmit signals from the CNS to effector cells (muscles, glands), while sensory neurons carry signals from receptors to the CNS. The PNS includes nerves and ganglia, and the CNS includes both brain and spinal cord.
Question 4 of 5
Neurotransmitters that open Na⁺ channels and trigger action potentials in receiving cells are called
Correct Answer: C
Rationale: Excitatory neurotransmitters (e.g., glutamate) depolarize the postsynaptic membrane by opening Na⁺ channels, increasing the likelihood of an action potential.
Question 5 of 5
The relationship between spinal nerves and the spinal cord is most like the relationship between
Correct Answer: C
Rationale: Spinal nerves branch off the spinal cord like roads from a highway, carrying signals to and from the periphery.
