Anatomy and Embryology of the Colon, Rectum, and Anus

  • Chapter
  • First Online:
The ASCRS Textbook of Colon and Rectal Surgery

Abstract

To truly understand surgical disease, one must have a comprehensive knowledge of the underlying anatomy and embryology. This chapter begins with a review of the anatomy of the rectum, anus, and pelvic floor. The anatomy of the colon is then discussed in a similar manner. Finally, the chapter concludes with a review of normal development, followed by a review of abnormal development and all of the disease states associated with abnormal development of the colon, rectum, and anus.
