A stroke is a kind of vascular brain injury ischemic in origin meaning there is decreased blood flow in one or more parts of the brain, most commonly caused by narrowing of arteries. The primary motor area is located in the frontal lobe, specifically the precentral gyrus or Brodmann area 4. Since the patient has lost motor activity on his right side of the body, then the more specific answer is the stroke is located in the left (contralateral because of decussation) frontal lobe, precentral gyrus.

Jill stepped on a tack. Which part of the central nervous system caused her foot to move off the tack quickly in a reflex respon
Veseljchak [2.6K]

Answer: Spinal cord.

Explanation:

The spinal cord of the central nervous system helps to move off quickly as a part of the reflex response. Jill stepped on a tack and suddenly he realizes that he should quickly move his legs out of the tack.

The pain is not stimulated until the signals reaches from the receptor to the brain. The formation of the reflex arc ensures that the amount of potential tissue damaged is less.

It forces the body to move quickly from the place that is causing damage.Example: Moving the leg up involuntarily when stepped on pin.

This occurs because the sensory neurons connects to the motor neurons within the spinal cord.This leads to the contraction of bones and muscles.

Hence, the correct option is spinal cord.
