Answer:
The intersection of branching nerves can be found in the submucosa layer of the gastrointestinal (GI) tract. The submucosa is a layer of connective tissue that contains blood vessels, lymphatic vessels, and nerve fibers. The nerves in the submucosa branch out and form a network called the submucosal plexus or Meissner's plexus. This plexus controls the secretions of the glands in the mucosa and the contractions of the muscularis mucosae.
