Anatomy of the abdomen and digestive system: illustrations

Antoine Micheau, Denis Hoa

Published on Tuesday 20 March 2012

SECTION: Anatomy of the thorax, abdomen, and pelvis

Images and anatomical references

This e-Anatomy module concerns the gross anatomy of the digestive system. We have especially focused on the diagrams of the abdominal digestive system, the oesophagus being treated in the modules on the thorax and the oral cavity and pharynx being included in the area of ENT. 83 anatomical diagrams and histological sections are captioned with over 300 structures.

This digestive anatomy tool is especially designed for students of medicine and paramedical studies.

 

 

Anatomical illustrations of the digestive system

 

 

All the anatomical illustrations are original and produced by Dr. Antoine Micheau. They were drawn in Photoshop or Illustrator using 3D modelling derived from medical imaging (principally abdominal scan).
The anatomical drawings are organised in a fairly classical manner so as to be easily usable as a standard anatomical atlas. The user navigates between different groups of images using the "Illustrations" tab:

  • Digestive system: general diagram showing all the major structures included in this system: mouth, tongue, oral cavity, teeth, buccal glands, throat, pharynx, oesophagus, stomach, small intestine (duodenum, jejunum and ileum), large intestine (colon, rectum, anal canal and anus), liver, gall bladder and pancreas. It should be noted that the spleen is not part of the digestive system but belongs to the lymphoid system, however it is still covered in this module because of its location close to the various digestive organs.
