The submucosal plexus, or Meissner's plexus, is primarily involved in the regulation of gastrointestinal secretion and local blood flow, not motility.

The main stimulation for production of A.D.H. is Decrease in blood volume - A.D.H. secretion increases during osmotic diuresis

the unique feature of S. gallinarum-pullorum compared to other Salmonella species is that it is always nonmotile. This is in contrast to the typical motility of Salmonella species, which is conferred by the presence of flagella.
