Current Question (ID: 14151)

Question:

Transverse section of gut shows four layers of the wall i.e serosa, muscularis, submucosa and mucosa. Which of the following statements is not correct regarding its arrangement and modification?

Options:

1. Serosa is the outermost layer which is made of thin mesothelium
2. Oblique muscle layer is present in stomach
3. All the four layers show modifications in different parts of alimentary canal
4. Villi and rugae are modified mucosal and submucosal layers respectively

Solution:

Villi and rugae are not modifications of the mucosal and submucosal layers respectively. Villi are finger-like projections that arise from the mucosa and increase its surface area for absorption. Rugae, on the other hand, are folds in the mucosa and submucosa that allow for the expansion of the stomach and increase its capacity.
