Neurological System Assessment Questions Questions
Question 1 of 5
________ contain only afferent fibers, long dendrites of sensory neurons.
Correct Answer: B
Rationale: Sensory nerves contain only afferent fibers, which are the long dendrites of sensory neurons. These fibers transmit sensory information from the body to the central nervous system. Cranial nerves and mixed nerves contain both afferent and efferent fibers, while motor nerves contain only efferent fibers. Therefore, sensory nerves is the correct answer as they exclusively carry afferent signals.
Question 2 of 5
The nerve that contains sensory fibers that are involved in hearing is:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A 75 year-old retired short-order cook presents to the office for evaluation of weakness. He has a history of hypertension; he stopped taking his medication a few months ago because he couldn't tell that it was making a difference and it was too expensive. On physical examination, his blood pressure is 220/110 mm Hg. He has deviation of the tongue to the left side. Which cranial nerve would have to be affected for this finding to be present?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
How does lateral inhibition work to specify individual neurons in the neural epithelium of invertebrates and vertebrates?
Correct Answer: A
Rationale: Lateral inhibition involves the Delta-Notch signaling pathway, where one cell in a cluster of prospective neurons becomes dominant by expressing higher levels of Delta. This cell inhibits its neighbors from adopting a neuronal fate through Notch signaling, ensuring that only a subset of cells differentiate into neurons. This mechanism is crucial for creating the precise pattern of neuronal distribution in the developing nervous system.
Question 5 of 5
Which of the following values is considered normal for ICP?
Correct Answer: A
Rationale: Normal intracranial pressure (ICP) ranges from 0 to 15 mm Hg. Elevated ICP, typically above 20 mm Hg, can indicate serious neurological conditions such as brain injury, hemorrhage, or tumors. Monitoring ICP is crucial in managing patients with head trauma or other brain pathologies to prevent further damage.
