The medulla oblongata mainly connects the human spinal cord to the cerebellum, and is a continuation of the spinal cord upward, bridging the brain and spine. There are many nerve centers in the medulla oblongata, including the respiratory center, the blood pressure center and the cardiovascular center. The specific location on the body surface is under the back of the head where it articulates with the neck, which is the projection area of the medulla oblongata body surface. A heavy blow to this area can cause severe damage. If the medulla oblongata is damaged, it can lead to cardiac and respiratory arrest or even death within a short period of time. The area below the back of the head that articulates with the cervical spine is very dangerous, so be careful to protect it from heavy blows to avoid serious injuries. Children sometimes fall, slip and fall backwards, easily injuring the medulla oblongata, and need to be very careful.
