Topographic anatomy of abdomen
4 likes1,459 views
The document provides a detailed overview of the topographic anatomy of the abdomen through 35 sections of cross-sectional views and corresponding CT scan images. Each section depicts the anatomical structures and their spatial relationships at different levels from T10 of the thorax down to L5 of the lumbar spine. Key structures highlighted in each section include organs such as the liver, kidneys, stomach and intestines as well as blood vessels like the inferior vena cava and abdominal aorta.
