A 49-year old female patient has limitation of left limbs arbitrary movements. Muscular tonus of left hand and leg is overstrained and spasmodic, local tendon reflexes are strong, pathological reflexes are presented. What is the most likely development mechanism of hypertension and hyperreflexia?
- A. Activation of synaptic transmission
- B. Reduction of descending inhibitory influence
- C. Inhibition of cerebral cortex motoneurons
- D. Activation of excitatory influence from the focus of stroke
- E. Motoneuron activation induced by stroke
Hint
Ask how a lesion of the motor cortex and its pathways changes the balance of drive acting on the spinal motoneurons and reflex arcs.
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.
