Does She Have a Uterus???

hello everyone welcome to the Institute

of human anatomy

I'm Jonathan this is Justin the voice of

tick-tock how's it going Justin what are

we gonna do today today we are going to

see if one of our cadavers has a yearís

we've been wanting to do this for a very

long time so we decided why not we've

also had a ton of social media requests

on female reproductive Anatomy and so

we're really excited to actually open

this body up and show the dissection

process and we're actually even excited

to find out if she even has a uterus

there's been plenty of bodies that have

come through labs that don't have a

uterus because of hysterectomy now when

we picked up the body of the body donor

program we didn't check for hysterectomy

scars on the abdomen however they can

still do the hysterectomy nationally so

we're still up in the air a little bit

on whether this female has a uterus for

us to observe yeah and she was in her

mid 90s and we've had her for about

three years now

or so and she was part of a dissection

course and so we decided just to take

off where they left off and we're just

gonna see if she has uterus all right

you ready to get started on this let's

do it okay


now as Justin mentioned in the intro

this was a body that was already used in

a dissection course by a group of

students and they already removed the

epidermis the dermis and the majority of

the hypodermis where I'm making the

incision you can see this white tissue

that's called the rectus sheath the

rectus sheath covers up the rectus

abdominis muscle which we all nicknamed

the six-pack muscle what's interesting

about that as I make an incision in the

anterior aspect of the body wall there's

only the rectus abdominis that I have to

go through whereas I move up to the

lateral aspect you actually have to go

through three muscles there the external

oblique the internal oblique and the

transversus abdominus one of the things

we need to make sure that we do is that

we just go through those muscles we want

to make sure that we don't go too deep

and actually cut through the structure

called the greater omentum that you'll

see when we reflect the body wall back

as well as the intestinal structures

that are going to be deeper to that now

right there Justin specifically going

through again that rectus abdominis and

moving laterally to go through those

three muscles that I mentioned

previously the obliques and the

transversus abdominus

now you can see that we've made it

through the lateral body wall here

through those three muscles that we

previously mentioned and we're just

making sure that we're separating the

tissues and not going too deeply into

the greater omentum or the small

intestine or even the ascending colon on

the side the justin's on

you can see on the right of the cadaver

Justin's pretty much all the way through

there and his hand is between the muscle

musculature and the greater omentum

which again is this mystery structure

that we haven't been able to show you

yet and you can see I'm almost through

there just cleaning up some of the or

separating some of the tissues


now coming back to that mystery

structure that I mentioned earlier the

greater omentum I'm about to reflect the

body wall back and you're not actually

going to see intestines you're going to

see this structure that is literally

almost like an apron that drapes over

the small intestine this greater omentum

is pretty amazing it's mostly made up of

fatty tissue as you can already see as

I'm reflecting the body wall back but it

doesn't actually attach down inferiorly

it actually attaches from the stomach

and wraps back up to attach to the

transverse colon and literally you can

just reflect the structure away as some

pretty cool functions that will mention

in another video so this is the greater

omentum we're sliding away here


there's yours yep

he found a uterus look at that so this

is uterus right here

it's a bra and ligament in there now

tubular structures in here but let's see

here do some more work here but she

definitely has a uterus alright so you

can see we've got the abdominal body

wall here we've made our incision to get

into the abdominal pelvic cavity

underneath this is where you'd see the

six-pack muscle which is technically

called the rectus abdominis but it's

covered up by this white tissue called

the rectus sheath now if we reflect this

we get down to a really cool structure

called the greater omentum now it just

looks like fatty tissue but it does have

adipose in there and so you would be

correct to think that there is adipose

in here but it's this really cool

structure that we're gonna do a

different video on but for now I'm just

gonna reflect it out of the way it

doesn't actually attach down here we did

not have to cut that away to remove it

literally just is this apron that covers

up the small intestine and the small

intestine you can see some of these

tubular structures here and this yellow

colored structure or tissue is called

the mesentery now the mesentery has a

whole bunch of blood vessels that can

actually absorb nutrients that are

moving through the small intestine it

also helps to intent a CH the small

intestine to the posterior body wall but

we're looking for the pelvic structures

that we've been talking about

specifically the uterus room literally

moving the guts out of the way so we can

see this structure here which is the

uterus now the uterus is draped with the

peritoneal tissue and so that creates

some structures here one being over here

this structure called the broad ligament

of the heater specifically where my

thumb is pinching I'll get it out of the

way but you can see me pushing up on

that structure if I come up a little


you can see this structure as well now

it's hard to see but if you look at it

and I trace it out for you this is

actually called the round ligament of

the uterus attaching up to the lateral

wall here coming back to the uterus the

very tip top here is referred to as the

fundus the majority of this region here

is referred to as the body of the uterus

to give you an idea of its width you can

see about from there to there and to

give context it's about where my finger

is as far as size it's a little bit

wider there some other structures we

definitely want to look at is this

structure hiding out underneath here let

me see if I can grab it for us is the

other structure down the way this is the

ovary right here the ovary we know

produces hormones also produces eggs and

you hear a lot of times women saying

that they're born if the number of eggs

that they have which is relatively true

there's also some other important

functions like we already mentioned

hormone release estrogens progesterones

things like that get released from the

ovaries and this structure again it's

draped in that peritoneal tissue so you

have to see there's a tube in there if

you were to come in and feel it you

could actually feel this tube that we

call the uterine tube also known as a

flow into attaching over to the ears

here and these structures coming off

here are the fimbriae

and these little finger like structures

losing things here actual flutter and a

track and ovulated egg into the uterine

tube to where it can be fertilized and

typically fertilization takes place

within the uterine tube then the

fertilized egg should descend down into

the uterus and actually implant now a

lot of times you hear about ectopic

pregnancies and that would be when a

fertilized eggs in fertilized egg

implants in this tube the fallopian or

more appropriately called the uterine

tube so hopefully that gives you kind of

an initial idea of some of the female

reproductive Anatomy we're definitely

gonna do some more stuff with this when

we do some more cleaning up with this

dissection but that's kind of our

initial tour here so we found a uterus

we're really excited that we were able

to show and share the female

reproductive structures with you guys

and what it actually takes to do this

process the section one's yeah this was

a lot of fun and we hope to do plenty

more of these in the future but for now

if you enjoyed this video be sure to

in the comments whatever you'd like to

see in future videos but until then

we'll see you the next one
