<span>The submucosa<span> 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.

</span><span><em>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.</em></span></span>

The action potential spreads through an axon by Group of answer choices depolarizing adjacent membrane to threshold, triggering
Step2247 [10]

The action potential spreads through an axon by depolarizing adjacent membrane to threshold.

  • K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.
  • Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.
  • Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.
  • Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is  is greater inside the cell than outside.
