 Here, everybody, Dr. O. In this video, we're going to cover the abdominal pelvic quadrants and regions. So it's the two different ways that we break the abdominal pelvic cavity down so we can talk about things, whether we're writing reports about where something happened surgically or where a patient has her symptoms, that kind of thing. So first, you will see that there are some typos on this page. It is quadrants. There's an extra N in there that shouldn't be there. I have a way funnier typo to share with you in just a moment though. So before we jump in, just remember when you're seeing lefts and rights, you're talking about the patients left and right. So on the screen here or on a piece of paper, the right side of the image would actually be the patients left. So just trying to get that confused. All right. So the simplest way to do it is just to break the body up into the, or the abdominal pelvic cavity into the four abdominal pelvic quadrants. So to see it, you just have a, you put a plus sign right through the umbilicus and there you have it. So let's just go through these quickly. Right lower quadrant. So when you're thinking right lower quadrant pain, if a patient's telling you a symptom that they're having pain in that area, um, the first thing you generally think with right lower quadrant would be potentially the appendix, appendicitis. Right upper quadrant pain, you would generally be thinking about the liver. Left upper quadrant pain, you'd be thinking about perhaps the pancreas or the spleen. And left lower quadrant pain, you're probably thinking about things like constipation, something going on with the large intestine. So those are the four abdominal pelvic quadrants. Now if you want to get more specific, we will break the abdominal pelvic cavity down into the nine regions. So I'll cover each of these terms here. So let's just go down one, let's just go down one of the sides and then we'll hit the middle. So we see the left and right hypochondriac region. So this is kind of interesting. The term hypochondriac, you generally think of someone that thinks they have every disease that they Google, but hypochondriac just means below the cartilage. So the reason that the hypochondriac region is named that is because it's right below the costal cartilage or the rib cartilage. Now the reason, I can't prove this, but the reason I think the term hypochondriac came into being is that if people had just diffuse abdominal pelvic symptoms below the ribs, they were considered a hypochondriac, but that we now know that a lot of gut problems can be related to all sorts of different diseases. So I think that whenever someone had a lot of diseases, they would have abdominal pelvic symptoms. I think that's where the term hypochondriac came from, but don't hold me to that. So the left and right hypochondriac region, right at the top, they have abdominal pelvic cavity there. Then we have left and right lumbar. So lumbar means loin. So there in the middle, we would have the lumbar regions, think lumbar spine, your low back. And then we'd have the left and right iliac region. Now you may see this called the inguinal region as well. So iliac and inguinal are both correct. It just depends on who's using the term. Okay, then let's go down the middle here. The epigastric region, epa means above and around. So epigastric above and around the stomach. So gastric means stomach, think stomach, think belly. So the epigastric region right there in the middle, then we have the umbilical region right around where the umbilicus is, your belly button. And then we have the hypo-gastric region, which means below or under the stomach. So the other term that can be used here is the pubic region. And that's what brings me to my typo. I can't share the image here because it's copyrighted. One of the first anatomy textbooks I ever taught out of actually accidentally called that the public region. So just my PSA, my public service announcement for this video. Please don't make the hypo-gastric region your public region. That is your pubic region. All right, so those are your nine abdominal pelvic regions. And here are your four abdominal pelvic quadrants. Get rid of that extra end. All right, have a wonderful day. Be blessed.
