Neurological System Assessment Questions Questions
Question 1 of 5
The Central Nervous System is made up of the:
Correct Answer: A
Rationale: The central nervous system (CNS) consists of the brain and spinal cord. It is responsible for processing and integrating sensory information and coordinating motor responses. The brain is the control center for thought, emotion, and behavior, while the spinal cord serves as a conduit for signals between the brain and the peripheral nervous system. The CNS plays a central role in maintaining homeostasis and responding to external and internal stimuli.

Question 3 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 4 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 5 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.
