Practice Question

After suffering an ischemic stroke, Cindy finds that she cannot move her left leg. Which area is most likely to have received damage from the stroke?

Answer Choices:

Correct Answer:

Right frontal lobe

Rationale:

↪ The frontal lobe is responsible for motor control, with the motor cortex controlling opposite (contralateral) body movements.

↪ Since Cindy cannot move her left leg, the lesion must be on the right side of her brain due to crossed motor pathways.

↪ The right frontal lobe, specifically the medial portion of the primary motor cortex, controls voluntary movement of the left leg.

↪ The temporal lobe is more involved with hearing and memory, while the occipital lobe is associated with vision.

↪ The insular lobe is linked with visceral sensation and autonomic function, not limb movement.
