Which layer of the alimentary canal contains not only glands and blood vessels but also a nerve plexus that regulate digestive activity?

The submucosa of the alimentary or the gastrointestinal tract contains numerous glands (i.e. gastric glands in the stomach, Brunner's glands in the duodenum) as well as numerous blood vessels. The submucosa also contains the submucosal nerve plexus or Meissner's plexus which functions to control the secretion of the submucosal glands.

Another layer that has a nerve plexus is the muscularis layer which has the muscular nerve plexus or Auerbach's plexus which control the contractions of the gastrointestinal tract. The Meissner's and Auerbach's plexus are collective called the enteric nervous system.

''Monocots and dicots differ from one another in four structures: leaves, stems, flowers and roots. Here we will discuss difference between the roots of the monocot and dicot plant. In monocot roots, the pericycle present just produce the roots, whereas, in dicot roots, the pericycle gives rise to roots, cork cambium.''
