Autonomic Nervous System NCLEX Questions Questions
Question 1 of 5
Sensation of pain:
Correct Answer: B
Rationale: Pain is transmitted via the lateral spinothalamic tract (B), not posterior columns (A, which carry vibration/position), nor the 9th cranial nerve (C, glossopharyngeal, mainly taste/pharynx). Perception involves the cortex, but not 'only' there (D). B is correct.
Question 2 of 5
Adaptation to sensory modalities:
Correct Answer: A
Rationale: Adaptation involves receptor fatigue (A, correct) or central inhibition. Rates vary (not B), Na+ channel inactivation (C) is partial, and inhibitory transmitters (D) are secondary. A is most accurate.
Question 3 of 5
The following is true about the vestibular system:
Correct Answer: D
Rationale: Vestibular system affects balance, not muscle tone directly (A). Semicircular canals detect angular acceleration (not linear, B), utricle detects linear (not rotational, C). Damage causes vertigo (D, correct). D is true.
Question 4 of 5
Which structure is associated with the embryologic development of the peripheral nervous system?
Correct Answer: A
Rationale: The neural crest (A) gives rise to the peripheral nervous system (PNS), including sensory and autonomic ganglia. The neuraxis (B) is the central nervous system (CNS) axis, rhombencephalon (C) forms brainstem and cerebellum (CNS), and neural tube (D) forms the CNS. A is correct.
Question 5 of 5
Which layer of the meninges surrounds and supports the sinuses that form the route through which blood drains from the CNS?
Correct Answer: A
Rationale: The dura mater (A) forms and supports venous sinuses (e.g., superior sagittal) for CNS blood drainage. The arachnoid mater (B) and subarachnoid space (C) handle CSF, and pia mater (D) adheres to the brain. A is correct.
