Location of Organs – Anatomy | Lecturio


this is a cartoon which are probably

really familiar with as you've gone

through your education and just the idea

of where the organs are within the

abdominal cavity so here we can see

we've got the sternum here now we can

see the Zippy sternum this inferior

limit of the sternum which demarcates

the superior aspect of the abdomen and

then we can see it radiating down in

this direction with those costal

cartilages we can see really clearly now

tucked up on this right hand side

protected by the ribs we've got the

liver this large organ the larger gland

in the human body and in the midline we

can see just about we've got the stomach

here which is then continuous with

what's called the duodenum and that's

the first part of the small intestine

but previously I mentioned the appendix

down in this lower was right inguinal

region and here we can see in the lower

right inguinal region we can actually

find the appendix so these are really

important landmarks which we can

identify in the abdominal cavity this is

an anterior view over here we've got a

posterior view and we can see where the

kidneys are located either side of the

vertebral column we can also see tucked

up over here we have the spleen which

you can just about make out on this left

hand side

so we'll look at the various positions

of these organs as we go through the

course but this provides a good general

overview so now we can relate the

surface landmarks that we spoke about

previously so a couple of these organs

like the liver and the appendix here we

can start off with the appendix this

blind pouch that's located at the

beginning of the large intestine by the

cecum and this is really important

because as I mentioned before we may

have radiating pain coming from this

region so a useful technique for

locating this pain is to use what's

known as McBurney's point and this is a

surface landmark for the appendix so

again we can remind ourselves of where

the umbilicus is we can see it here we

can remind ourselves aware the anterior

superior iliac spine is and as we can

see in the diagram we can draw a line

between these two regions a third of the

way from the anterior superior iliac

spine towards the umbilicus so about a

third of the way across we can locate

our appendix and that's known as

McBurney's point palpation in this

region can lead to quite severe acute

pain and this could indicate that the

patient maybe has appendicitis so that's

where the surface landmarks are really

important in being able to identify

which organs lie deep to the skin we can

also see over on this side again

mentioned it in the previous slide the

position of the liver and here we can

see that actually the liver is hard to

palpate because most of the liver is

actually covered by these ribs and here

this diagram may not be a hundred

percent correct in that it's quite

unusual for the liver to actually be so

clearly observed three of the ribs is

usually only in patients that have an

enlarged liver that it can actually

radiate below the ribs and to palpate

the liver you can feel this costal

margin and asking the patient to breathe

in and out moves the liver and you can

actually pressing on the skin deep to

these ribs can feel this edge of the

liver pressing against your fingers

so it's really important that we

mentioned the surface landmarks as you

can use them to try and feel and locate

organs deep to the skin you just
