Assertion : Auerbach's plexus controls the secretion of intestinal juice. Reason : Meissner's plexus controls the peristalsis in alimentary canal.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
  • C
    If assertion is true but reason is false.
  • Correct answer
    D
    If both assertion and reason are false.

Solution

Auerbach's plexus is a network of nerve cell and parasympathetic nerve fibre present in the muscularis layer of wall of alimentary canal. It controls peristalsis. On the other hand, Meissner's plexus is a network of nerve cells and sympathetic nerve fibre present in the submucosa layer of wall of alimentary canal. It controls the secretion of intestinal juice.

Hence, the correct answer is option: 'D'.
