KROK 1 2018 – Question 92 · KROK (Medicine) · Pathophysiology
The right leg of a 40-year-old woman measured at the shin level is by 2 cm smaller in the diameter than the left leg. Ankle-jerk (Achilles) and knee-jerk reflexes are absent on the right. What is the most likely mechanism of hyporeflexia development during peripheral paralysis?
- A. Activation of excitatory impulses from the CNS
- B. Disturbed conduction of stimulation
- C. Inhibition of pyramidal motoneuron
- D. Disturbed perception of stimulation
- E. Disturbed synaptic impulse transmission
Hint
In peripheral paralysis with muscle wasting and lost tendon reflexes, ask which link of the reflex arc is damaged and what the signal can no longer do there.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
