Four Abdominal Quadrants and Nine Abdominal Regions - Anatomy and Physiology

Four Abdominal Quadrants and Nine Abdominal Regions – Anatomy and Physiology



in anatomy and physiology you'll learn how to divide the abdomen into non different regions or four different quadrants if you plan to enter a healthcare profession such as nursing this is something you'll use on the job when performing abdominal assessments and while documenting first let's take a look at the four quadrants which are created by an intersecting horizontal plane also called the trans umbilical plane and a median plane the four quadrants are easy to remember because they consist of a left upper quadrant less lower quadrant right upper quadrant and right lower quadrant now there are two important things you'll want to remember when dealing with the four quadrants the first thing is that the navel or belly button is the major landmark in determining where the four quadrants are located because again this is the point where those two planes intersect which create the four quadrants the second thing you'll want to remember is that right and left are from the perspective of the person in the anatomical position so when you're looking at it a lot of times it'll look flip or backwards and that will throw a lot of people off so always remember this will be the right upper quadrant this will be the right lower quadrant this will be the left upper quadrant and this will be the left lower quadrant from the anatomical position now let's take a look at some of the major organs in the four quadrants in the right upper quadrant we see the liver the stomach the gallbladder the duodenum the right kidney the pancreas and the right adrenal gland in the left upper quadrant we have the liver stomach pancreas left kidney spleen and the left adrenal gland the right lower quadrant contains the appendix reproductive organs and the right ureter and the left lower quadrant contains the left ureter reproductive organs and all four quadrants as you can see here contain portions of the small and large intestines now let's talk about the non abdominal regions and these regions divide the abdomen into even smaller sections by using two parasagittal planes that run down the middle of the clavicle bone also called midclavicular planes and two horizontal or transverse planes the superior transverse plane is called the sub costal plane and in this located just below the ribs the intertubercular plane is the inferior transverse plane and it intersects the tubercles of the pelvis running just inferior to the navel now it is important for you to know the names and locations of these non abdominal regions so here are some tips for remembering them first let's cover the right and the left columns because they have the same exact name it's just that one will be a left side and one will be a right side and these are unique because the regions on the side are named after the bones that they are closest to so first let's talk about the left and right hypochondriac region the prefix hypo means below or under and the word Condor react means cartilage which is referring to the cartilage of the ribs so when we put the name together we have the abdominal region that is under the ribs easy next we have the left and right lumbar regions and the word lumbar is referring of course to the lumbar vertebra and your lower back kind of between the ribs and the pelvis and this is going to be nearest that side portion right there so that's why they call it the lumbar region next we have the left and right iliac region and the top of the hip bone has what's called the iliac crest and that's what this region is closest to it's closest to the hip bone where the iliac crest is and so they call it the iliac region now that's pretty simple and that takes care of the left and right columns but now let's look at the abdominal regions in the center column and unlock the regions on the side these center column regions are named after their location relative to the stomach not the bones so first we have the epigastric region and the prefix epi means above or over and gastric means stomach or belly therefore when you put the name together this is the region over and above the belly next we have the umbilical region and this is really easy to remember because this contains your navel which is also called the umbilicus and again when you think about the four quadrants the navel is the point where those two planes intersect well in the nine abdominal regions the navel is going to be located within that center region so that will help you remember the umbilical region and then finally we have the hypogastric region and we've already learned that hypo means below or under and gastric refers to the stomach or belly so when we put the word together we know that the hypo gastric region is below the belly now if you need a quick memory trick to keep these reasons straight in your mind remember that for either of the side columns we have hypochondriac then lumbar then iliac so we have an H and L and an eye and then in the middle region we have epigastric umbilical and hypogastric so we have an e au and an H and I just remember this sentence Hector loves Isabel every unceasing hour I love a good love story now let's take a look at some of the major organs that you'll find in each of the nine regions and in most basic anatomy courses professors probably don't expect you to memorize a whole list of organs that you'll find in each region but you do need to have a general understanding of where these major organs are located in the grand scheme of things so for the right hypochondriac region you'll find organs such as the liver gall bladder right kidney and portions of the small and large intestine in the epigastric region you'll find portions of the liver as well as the stomach pancreas duodenum spleen and adrenal glands in the left hypochondriac region you'll find the spleen the large and small intestines the left kidney pancreas stomach and tip of the liver in the right lumbar region you'll find portions of the ascending colon small intestine and the right kidney and the umbilical region you'll find the duodenum the small intestine as well as the transverse colon in the left lumbar region you'll find parts of the descending colon the small intestine and the left kidney in the right iliac region you'll find the appendix the cecum the ascending colon and the small intestine in the hypogastric region you'll find the bladder portions of the sigmoid colon the small intestine and reproductive organs and in the left iliac region you'll find parts of the sigmoid colon the descending colon and the small intestine now you can take our free quiz to test your knowledge over this subject by clicking the link in the description below in addition we have a whole anatomy and physiology
