3 Abdominal Sections

Abdominal Sections:

Imagine you’re plotting out your next great adventure through a massive city. You could draw a 3×3 grid over your map, dividing it into nine distinct zones like a tic-tac-toe board. Or, if you’re feeling a bit less ambitious, slap on a 2×2 grid and voilà—you’ve got four manageable chunks. This nifty trick helps you break down the sprawling metropolis into bite-sized areas for easier exploration.

Now, think of anatomists doing something similar, but with the human body. They use quadrants and/or regions to pinpoint different organs.

View the following images to get better acquainted with each sectioning plane. Understanding each format can help foster an understanding of mapping structures on the fly!

View the right diagram of Figure 3. It can be divided into these segments:
