Test Questions on Autonomic Nervous System Questions
Question 1 of 5
Which of the following is in the peripheral nervous system?
Correct Answer: D
Rationale: Satellite cells are PNS glial cells supporting neuron cell bodies in ganglia. The others are CNS-specific (oligodendrocytes myelinate, ependymal line ventricles, microglia are immune).
Question 2 of 5
While teaching the client about a diagnosed endocrine disorder, which area of the brain would the nurse include as the center in the brain that regulates hormone production?
Correct Answer: B
Rationale: The diencephalon (hypothalamus, pituitary) regulates hormone production. Cerebrum handles cognition, brainstem vital functions, cerebellum coordination.
Question 3 of 5
Neuropeptides are:
Correct Answer: A
Rationale: Neuropeptides are small protein-like molecules that act as neurotransmitters or neuromodulators, released by neurons to communicate with other cells. They are not glial cells, not produced by the choroid plexus (which makes CSF), nor nutrients.
Question 4 of 5
Tracts of white matter which connect the right and left hemispheres are composed of:
Correct Answer: C
Rationale: Commissural fibers (e.g., corpus callosum) connect the right and left cerebral hemispheres. Decussation fibers cross midline, association fibers connect within one hemisphere, and projection fibers link cortex to lower structures.
Question 5 of 5
The corpora quadrigemina, composed of the superior and inferior colliculi, is located in the:
Correct Answer: B
Rationale: The corpora quadrigemina (superior and inferior colliculi) are in the mesencephalon (midbrain), processing visual and auditory reflexes. Telencephalon is cerebrum, diencephalon includes thalamus, metencephalon is pons/cerebellum.
