Lesson Transcript
Instructor: Artem Cheprasov

Artem has a doctor of veterinary medicine degree.

Like we can divide a city, state, or country, your abdomen can be divided into many different regions for the purposes of study, reference, and practice. We will define all nine of the abdominal regions in this lesson.

Mapping the Abdomen

Hey! You know how people like to map things out to make it easier to locate one thing or another? Doctors and scientists do this all of the time, too. Instead of saying, 'Hey, look over there,' they can be more specific and say something like, 'look in the right iliac region.'

So, without further delay, let's go over the names of the regions of the abdomen used in medicine.

Hypochondriac & Epigastric Regions

Since we're mapping out the body into regions, let's get into a little car and take a tour of all of them.

abdominalregions

The first area is the right hypochondriac region. The hypochondrium is the upper portion of the abdomen, just below the lowest ribs. Hypo- stands for below, and chondro refers to the cartilage of the ribs.

As we drive here we find part of the liver and make our way past part of the right kidney.

Moving right on our map, we enter the epigastric area, where epigastric means above the stomach, because epi- means above, and gastric refers to the stomach.

Here we hear the stomach and parts of the intestines grumble and carefully make our way past the digestive enzymes of the pancreas. As we move even further to the right, we encounter the left hypochondriac region, where we find part of the stomach, pancreas, left kidney, and intestines.

Lumbar & Umbilical Regions

From there, we drive down to the left lumbar region, with lumbar referring to of or near the lower back, between the lowest ribs and pelvis. In the left lumbar region, as we drive over this area, we hear imaginary droplets of liquid as urine is produced by the left kidney and more grumbling of the colon and intestines.

Left of this region on our map is the umbilical region, with umbilical referring to the navel. We have to be careful to avoid the pothole in this area of the abdomen, the belly button; I don't feel like changing blown tires! As we carefully navigate it, we make our way over the parts of the kidneys and intestines found in this area.

Then we arrive in the right lumbar region, where part of the right kidney is found, as well as the intestines and colon.

Iliac, Inguinal, & Hypogastric Regions

Heading south on our map from this region, we make our way into the right (inguinal) iliac region. Inguinal means pertaining to the groin, and iliac means pertaining to the hip bone.

This area of the map pains me, as it's where the famous appendix is at. It's also where the right ovary in females is found as well as parts of the intestines and colon.
