Answer:
Solution:
The mucosa of the small intestine forms villi, which are lined by cells that produce numerous microscopic projections called microvilli, giving a brush border appearance.
The villi are supplied with a network of capillaries and a large lymph vessel called the lacteal.
The mucosal layer also forms crypts in between the bases of villi in the intestine, known as crypts of Lieberkuhn.
Brunner's glands are present in the submucosal layer of the duodenum, not in the mucosal layer. Therefore, the statement regarding Brunner's glands being present in the mucosal layer is incorrect.
Answer: Brunner's glands present in the mucosal layer help in the action of goblet cells.
