Pediatric Neurological NCLEX Questions Questions
Question 1 of 5
Which of the following tracts providafferent information for spinovisual reflexes:
Correct Answer: D
Rationale: Spinotectal. The spinotectal tract carriafferent sensory information (e.g., pain, touch) from the spinal cord to the tectum (superior colliculus) in the midbrain, contributing to spinovisual reflexlike head/eye turning toward stimuli. Choice A (anterior spinothalamic) is for crude touch to thalamus. Choice B (lateral spinothalamic) is for pain/temperature. Choice C (posterior spinocerebellar) is for unconscious proprioception to cerebellum. Thus, D correctly identifithe spinotectal tracts role, making it the right answer.
Question 2 of 5
Whats correct about dorsal spinocerebellar tract:
Correct Answer: A
Rationale: contains 2nd order neurons from clarks nucleus that originate from the lower limbs . The dorsal spinocerebellar tract carriunconscious proprioception from lower limbs via second-order neurons in Clarknucleus (T1-L2), entering the cerebellum through the inferior peduncle. Choice B is wrong (upper limbs use cuneocerebellar tract). Choice C is incomplete. Choice D is false (A is correct). Thus, A accurately describthe tract, making it correct.
Question 3 of 5
Regarding Anterior corticospinal tract, choose the WRONG statement:
Correct Answer: D
Rationale: 55% of its fibers synapse in the upper cervical region . The anterior corticospinal tract, uncrossed, acts on axial muscl, passthrough the pons basilar part and midbrain pedunculi , but only about 10-20% remain uncrossed, with most synapsing lower, not 55% in cervical. Thus, D overestimatcervical synapses, making it the wrong statement and the correct answer.
Question 4 of 5
The cerebral area which is responsible for production of fine movements of hand is located:
Correct Answer: D
Rationale: In front of the central sulcus. Fine hand movements are controlled by the primary motor cortex, in the precentral gyrus, anterior to the central sulcus. Choice A (temporal gyrus) is for audition. Choice B (postcentral) is sensory. Choice C (medial brain) includleg areas. Thus, D correctly locatthe hand motor area, making it correct.
Question 5 of 5
Which of the following regions of white matter would not contain corticospinal fibers:
Correct Answer: D
Rationale: Anterior limb of the internal capsule . Corticospinal fibers travel through the posterior limb of the internal capsule, not anterior (frontopontine fibers). Choice A (medulla pyramid), B (lateral column), and C (cerebral peduncle) all contain corticospinal fibers. Thus, D is the exception, making it correct.
