[Fecal incontinence--anatomy/pathophysiology].

Area of Science:

• Embryology
• Anatomy
• Physiology

Context:

• The ano-rectum originates from the proctodaeum and hindgut.
• The uro-rectal septum separates the hindgut from the cloaca.
• Shared vascular and neural origins with the uro-genital sinus.

Purpose:

• To elucidate the embryological development of the ano-rectal region.
• To establish the anatomical and topographical basis for continence and defecation.
• To highlight the necessity of embryological studies for understanding anorectal structures.

Summary:

• The ano-rectal organ's development involves the proctodaeum and hindgut, separated by the uro-rectal septum.
• Its shared embryological origin with the uro-genital sinus influences its neurovascular supply.
• Embryological insights are crucial for comprehending anorectal anatomy, physiology, continence, and defecation.

Impact:

• Provides foundational knowledge for understanding ano-rectal function.
• Emphasizes the critical role of embryology in clinical anatomy.
• Aids in diagnosing and managing congenital anorectal malformations.
