Anatomy of Anal Canal Made Easy | Pectinate Line, Sphincters, Venous Plexuses & Applied Anatomy

In this video: Anatomy of Anal Canal Made Easy

Understand the detailed yet simplified gross and surgical anatomy of the anal canal through step-by-step visuals and clear explanations.

Topics Covered:
• Location, extent, and peculiarities of the anal canal
• Anterior, posterior, and lateral relations of the anal canal
• Simple line diagrams to visualize complex structures
• Division of the anal canal into three parts — upper, middle, and lower
• Pectinate line and Hilton’s line explained
• Internal and external anal sphincters and their roles in continence
• Anorectal ring and its clinical importance in fecal control
• Facial planes and outer longitudinal muscle layer of rectum and anal canal
• Internal and external venous plexuses — their connections and clinical relevance
• Superior, middle, and inferior rectal veins and portocaval anastomosis
• Anal columns, valves, papillae, sinuses, and glands
• Developmental correlation of anal canal and its blood and nerve supply
• Anal fistulae — classification based on anatomical position
• Lymphatic drainage and applied aspects
• Types of anal canal — surgical, anatomical, and real
