A patient with Parkinson's disease demonstrates micrographia and bradykinesia. Which brain structure is primarily affected?
Answer: Basal ganglia (substantia nigra)
Parkinson's disease involves degeneration of dopaminergic neurons in the substantia nigra of the basal ganglia.
Berg Balance Scale scores of 0–20 indicate:
Answer: High fall risk requiring wheelchair
A Berg Balance Scale score of 0–20 indicates high fall risk, and the patient is likely wheelchair dependent.
Which cranial nerve is tested by the gag reflex?
Answer: CN IX and X
The gag reflex involves the glossopharyngeal (CN IX) as the afferent limb and vagus (CN X) as the efferent limb.
In peripheral nerve regeneration, the approximate rate of axon regrowth is:
Answer: 1–3 mm/day
Peripheral nerve axons regenerate at approximately 1–3 mm per day after injury.
A patient post-CVA has difficulty recognizing objects by touch with eyes closed. This is called:
Answer: Astereognosis
Astereognosis is the inability to identify objects through tactile exploration without visual input.
Which reflex is used to assess the S1 spinal level?
Answer: Achilles reflex
The Achilles (ankle jerk) reflex is mediated by the S1 nerve root.
