    Area of Science:

    • Gastroenterology
    • Colorectal Surgery
    • Pathology

    Background:

    • The structural understanding of the colon varies significantly based on the examination methodology employed.
    • Perspectives differ among radiologists, endoscopists, surgeons, pathologists, and electron microscopists.

    Purpose of the Study:

    • To review the gross, macroscopical, histological, and ultrastructural anatomy of the normal colorectum.
    • To emphasize structures crucial for colorectal secretion and motility.
    • To highlight interspecies differences in colorectal anatomy.

    Main Methods:

    • Review of existing literature on colorectal anatomy.
    • Comparative analysis of different examination techniques and their resulting structural interpretations.
    • Histological and ultrastructural examination of colorectal tissues.

    Main Results:

    • The interpretation of colon structure is method-dependent, with distinct viewpoints from various medical specialists.
    • Key structures for secretion and motility, including the mucosa and muscularis propria, are detailed.
    • Significant anatomical variations exist between human and animal colorectal structures.

    Conclusions:

    • A comprehensive understanding of colorectal structure requires integrating knowledge from diverse methodologies.
    • The mucosa and muscularis propria are central to colorectal function.
    • Caution is advised when extrapolating findings from animal models to human colorectal physiology.
