Areas of the Abdomen

Overview

The abdomen contains several defined anatomical regions that guide understanding of organ relationships, surgical planes and patterns of disease. This section introduces the core spaces and triangles that shape abdominal anatomy and clinical assessment.

Key Structures

Topics include the abdominal cavity, peritoneum, inguinal canal, Calot’s triangle and Hesselbach’s triangle. Each page outlines boundaries, contents and the significance of these regions in surgical and anatomical practice.

Clinical Relevance and Learning Focus

Knowledge of abdominal areas supports interpretation of hernias, gallbladder pathology, peritoneal spread of infection and operative approaches. These regions provide essential landmarks for examination, imaging and surgery.
