A patient with a C6 spinal cord injury would be expected to have intact function of which muscle group?
Answer: Wrist extensors
C6 innervates the wrist extensors (extensor carpi radialis longus and brevis), which remain functional at this level.
Which type of neuroglial cell is responsible for forming myelin in the central nervous system?
Answer: Oligodendrocytes
Oligodendrocytes produce myelin sheaths around axons in the central nervous system.
A patient presents with intention tremor, dysmetria, and dysdiadochokinesia. Which brain structure is most likely affected?
Answer: Cerebellum
Intention tremor, dysmetria, and dysdiadochokinesia are classic signs of cerebellar dysfunction.
During nerve conduction velocity testing, which finding is most consistent with demyelinating neuropathy rather than axonal neuropathy?
Answer: Significantly reduced conduction velocity
Demyelinating neuropathies characteristically show markedly reduced conduction velocity due to impaired saltatory conduction.
A patient with Parkinson disease demonstrates a shuffling gait pattern. Which neurotransmitter deficiency is primarily responsible for this motor dysfunction?
Answer: Dopamine
Parkinson disease results from degeneration of dopaminergic neurons in the substantia nigra, leading to characteristic motor deficits.
Which reflex would be expected to be ABSENT in a healthy 12-month-old infant?
Answer: Asymmetrical tonic neck reflex
The asymmetrical tonic neck reflex is typically integrated by 6 months of age and should be absent by 12 months.
