Where will the brain send nerve impulses or hormones if the blood flowing through it contain too little glucose?

If the blood flowing through the brain contains too little glucose, the brain will respond by sending nerve impulses to stimulate the release of hormones like glucagon and epinephrine. These hormones promote the breakdown of glycogen in the liver to release glucose into the bloodstream. Additionally, the brain may trigger the sensation of hunger to encourage food intake, aiming to restore glucose levels. Overall, these actions help maintain energy supply for critical brain functions.
