Where does the ventral nerve cord encircle the digestive tract and join with the brain in a grasshopper?

In a grasshopper, the ventral nerve cord encircles the digestive tract at the anterior end, where it connects to the brain. This connection occurs in the head region, specifically around the esophagus, forming a structure known as the subesophageal ganglion. This arrangement allows for coordinated control of the nervous system and digestive functions.
