Question 1 of 5
What does the experiment in which a frog's eye is rotated tell us about the spatial relationships between the retina and the tectum?
Correct Answer: B
Rationale: The frog eye rotation experiment demonstrates that retinal axons have an intrinsic map of their position. Nasal (anterior) neurons project to the posterior tectum, and temporal (posterior) neurons project to the anterior tectum. This shows that spatial information is encoded within the retina and guides axon targeting.
Question 2 of 5
Gray matter differs from white matter because gray matter _________ and white matter ______.
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
The nurse is preparing material about the neurological system as part of a major presentation. What should the nurse include that explains the purpose of white matter?
Correct Answer: A
Rationale: White matter consists of myelinated nerve tracts that carry sensory or motor impulses within the central nervous system. It does not contain white blood cells, protect spinal nerves, or regulate movement directly. Understanding the function of white matter is crucial for explaining how information is transmitted in the nervous system.
Question 4 of 5
The nurse is caring for a patient who is scheduled for a magnetic resonance imaging (MRI) scan. What explanation should be provided to the patient and family?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The human nervous system is capable of a wide range of functions. What is the basic unit of the nervous system?
Correct Answer: C
Rationale: The neuron is the basic unit of the nervous system, responsible for transmitting information through electrical and chemical signals. Glial cells support neurons, meninges are protective layers around the brain and spinal cord, and cerebrospinal fluid cushions the central nervous system. Understanding the neuron's role is fundamental to studying nervous system function.
