G08: Overview of the Abdomen and Anterior Abdominal Wall (Dr. Albertine)

At the end of this lecture, students should be able to master the following: 1) Overview

a) Identify the functions of the anterior abdominal wall b) Describe the boundaries of the anterior abdominal wall 2) Surface Anatomy a) Locate and describe the following surface landmarks: xiphoid process, costal margin, 9th costal cartilage, iliac crest, pubic tubercle, umbilicus


3) Planes and Divisions a) Identify and describe the following planes of the abdomen: transpyloric, transumbilical, subcostal, transtubercular, and midclavicular

b) Describe the 9 zones created by the subcostal, transtubercular, and midclavicular planes c) Describe the 4 quadrants created by the midline and transumbilical planes and describe their clinical utility d) Identify the vertebral levels associated with the following landmarks: xiphoid process, transpyloric plane, subcostal plane, umbilicus, and iliac crest


4) Structure of the Anterior Abdominal Wall a) Identify and describe the layers of the anterior abdominal wall from superficial to deep (skin, Camper's fascia, Scarpa's fascia, deep investing fascia, abdominal muscles, tranversalis fascia, extraperitoneal fascia, parietal peritoneum)

5) Vasculature a) Describe the arterial and venous collateral circuitry of the anterior abdominal wall (superior epigastric, inferior epigastric, deep circumflex iliac, superficial circumflex iliac, superficial epigastric arteries and veins) b) Describe the lymphatic drainage of the anterior abdominal wall (superficial and deep)


6) Innervation a) Understand the segmental innervation of the anterior abdominal skin and musculature -The navel dermatome is T10 (belly but"ten") b) Describe the cutaneous and muscular distribution of the following nerves: lower five intercostal, subcostal (T12), iliohypogastric (L1) and ilioinguinal (L2) nerves
