Photographic reconstruction of the intestine wall observed with the objective of 10x. Going from outside inwards we can see the following layers: serous, external and internal muscular, submucous and mucous. The last one contains numerous crypts of Lieberkühn in contact with the  intestinal lumen. Between both muscular layers we can notice some nervous ganglia, corresponding to the Auerbach's plexus. Details of the serous, muscular and mucous are observed at higher magnification in other microphotographies (zones framed in red, yellow, and blue, respectively)
