Here, 10 or 12 cranial nerves start.

Shields the stomach wall from the gastric juices' acidity.

Correct! Wrong!

Mucus is the substance that protects the stomach wall from the acidity of gastric juices. The stomach lining produces a layer of mucus that covers its inner surface, acting as a protective barrier. Gastric juices, which include hydrochloric acid and enzymes, are secreted by the stomach to aid in digestion. However, these juices are highly acidic and can potentially damage the stomach wall. The mucus layer acts as a physical barrier, preventing direct contact between the gastric juices and the stomach lining. It helps to maintain a suitable pH and protect the stomach tissues from the corrosive effects of the acidic environment.
