Welcome to Anatomy & Physiology at Glen Oaks Community College I'm Dr. Ren Hartung
I'm going to do something a little bit different for this one and look at the endocrine system
we'll go through all of the endocrine glands in then I'll quiz you on those glands
So, we're just looking at anatomy on some of the models--- this is a brain model
and of the endocrine glands that we see up in the brain
back here we have the pineal gland
and then over here under the thalamus we have the hypothalamus
and then down here we have the pituitary gland
So, those of the endocrine glands that we see in the brain--
let's look at a few different torso models that have the structures--
This one doesn't really have a brain that had the endocrine glands, but in the neck we have an unpainted
thyroid gland (the thyroid gland is in the neck) the parathyroid gands by the way are behind the thyroid
they are four little nodules on the back of the thyroid on either side
moving down, the thymus would be in this location, but this model did not have a thymus
the adrenal glands, this is the right adrenal gland, this is the left adrenal gland
and for this model for pancreas if I lift up this piece
it fits woops, it fits inside here
like so
and that yellow bit in the middle is the pancreas
so if I set it down here
we actually have three structures here we have the pancreas in the middle
and then over here we have the spleen and at the other end we have of the small intestine
this model didn't have any reproductive organs, so let's move on to the next torso model
this is also relatively inexpensivetorso model, it does have a brain
that can be removed
but it doesn't really have a pituitary gland, and you can kind of see where the pineal gland would be and where the hypothalamus is
but it doesn't really have a pituitary so, lets go to the neck, this is a nicely painted
thyroid in the neck, showing you that butterfly shape of the thyroid gland
and remember that the parathyroids are behind the thyroid gland they're on the back of the thyroid gland
again in this basic area here would be the thymus but this model also doesn't have a thymus
this is the right adrenal gland
this is the left adrenal gland
both above the kidneys and home for this one the pancreas is on the gut package if I take
the intestine package and set it up in here
this thing up here on top of it which, if you can see the surface it has kind of glandular appearance parents that's supposed to be the pancreas
so that's pancreas.
and reproductive organ wise, the gonads on this model has female reproductive organs that set in here like this
if I take it and put it sideways you can kind of make out where the uterus is, where the bladder is,
where the vagina... these are female reproductive organs
and the thing and tapping on with my finger
would be the right ovary
so that's the first time we've seen a gonad so far
moving on to a much larger and more complicated torso model
this torso model had half of a brain up here that all up but on the bench
this
would be the pineal gland back here
then we have thalamus, therefore this is hypothalamus in this region.
The pituitary would be hanging off here but what they did for this torso model
is they left it inside of the skull, they left it lying inside of that feature of the sphenoid bone you might remember call the sella turcica
so that's where the pituitary gland is in this model
that's go down to the neck
there is thyroid gland
for this model I actually left in the heart because the thymus gland llies on top of the heart in this area here, but again...
my models don't have thymus on them--- let's go down to the abdomen where we have the right adrenal gland
and the left adrenal gland
and then below those we have the pancreas
notice that this pancreas has been dissected open to show the pancreatic duct,
that's because because the pancreas has not only endocrine function making insulin and glucogon
those hormones but also look at it produces pancreatic juice which is important for the digestive system
so again that's pancreas-- and if we go down into the pelvis of this model right now it's got female organs in it
this is the uterus this would be to left over and this would be the right ovary over here
solos of the female gonads
moving on to my other torso model I've got a nice older good detailed torso model here
here's the half of the brain so back in this neighborhood here would be the pineal gland
up here or more forward is the hypothalamus below the thalamus
and then down here is the pituitary gland
I haven't mentioned infundibulum before but this little bit here that attaches the pituitary
to the brain or attaches the pituitary to the hypothalamus
that's call the infundibulum.
let's go to the neck in this torso model
there's the (sorry the focus isn't working really well)
there's the thyroid gland
and then down the chest to be the thymus
down lower I'm gonna remove the stomach right now so we can easily see
the rights adrenal gland about kidney and left adrenal gland above left kidney
and I'm gonna pull the stomach backup here and it's proper position roughly, that's where the stomach lies
and behind the stomach right there that little bit of yellow there that you see--- that is the umm
pancreas. If I turn that stomach around you can see it really nicely
that's the pancreas and again this one is also been opened up to show the pancreatic ducts
this model also is one of those it wasn't given a sex so we don't have any gonads for this model
let me really quickly show you the male gonads--- if I come over here
this is a pelvic model that's useful you can nicely see in this case right testicle
and on the other part of the model we had left testicle
so those would be the male gonads
I have another model model what it comes out of one of the larger torso models we were looking at over there this of course
is the male reproductive
structures and there would be
right testicle
and the left testicle is not visible it's behind these tissues-- inside of the scrotum over here
and I think that's pretty much all
of the endocrine system , that's about all of the endocrine system I wanted to show you
I'll go on moving to quiz mode now
What I'm going to do is I'm going to point to different endocrine glands
and then you try to remember name what they are
I recommend that you write it down while you're doing it
Pause the video is you need to 'cause directly after asking about them I'm going to give you the answer
let's start wiht this torso model here and let's go down here
what gland is this?
and the answer is this is the left adrenal gland,
it's above the kidney you can see a piece of the kidney there, this is above that kidney, so this is the left adrenal gland
how about to go down to this model's brain
and we'll ask what is this endocrine gland back here?
the answer to that is that this is the pineal gland
and then, let's stay with the same model and go inside the skull stay with the than endocrine gland is in the home
in the brain and are enough to bring into a
what is this gland
and again that land is sitting in the tella--- sella turcica
it's the pituitary gland
let's go down here--- how about this gland herethis kind of longish one that comes up against the spleen.
the answer to that is pancreas this is the pancreas
and then let's go down here into the pelvic cavity
what is this gland?
and the answer to that is that this is the left ovary
and of course on the other side we have the right ovary
lets jump a little bit, let's go to this other model here, the smallest one that I have... What is this gland here?
the answer that is the thyroid, this is the thyroid gland
how about this gland down here?
that would be the right adrenal gland
and of course a left adrenal gland is over here
how about for this little model what is this yellow gland here?
that again as the pancreas
for this model let's put the intestines up here
I know it's not easy to see because it's not painted differently
but, if I can get it to sit there, what is this gland here?
that is the pancreas notice of the pancreas runs between the small intestine
and goes up towards the spleen, that's one way to help you
notice what it is even if it looks different from a model you're used to
since we're still here, lets ask what this one is. What gland is this?
that's the right adrenal gland
and then let's go up here, what gland would be right here in the chest
into that is the thymus
and as long as we're here let's go a little bit north what is this gland?
and again this is the thyroid gland
let's jump to this other big torso model up here
we'll actually go down to its brain
what is this going here
the answer to that is the pituitary gland and you can actually see the sella turcica that it rests in, that feature of the sphenoid bone
all about this gland back here?
the answer to that is the pineal gland
and then how about over here?
this gland is the hypothalamus
and by the way, this piece here between
the pituitary gland and the hypothalamus what we call that?
that's called the infundibulum
let's go ahead and jump into this torso models larger bits
what gland is this?
the answer is the thyroid gland
and while we're talking about the thyroid gland, what lies on the back of the thyroid gland
and the answer is the parathyroid glands
what's here in the chest again?
but not visible, what gland?
again it's the thymus. Let's look down here in the abdomen-- what gland would this be?
and the answer is the right adrenal gland
therefore this must be what
the answer is the left adrenal gland. Let's look down here behind stomach what gland would this be?
the answer to that is pancreas
let's move on to gonads
what would this endocrine gland be?
this one this is the right testicle
and left one is covered up by tissue, the right one is visible with this model
then let's look at the female
what would this endocrine gland be?
and the answer to that is the left ovary.
therefore on the other side we have the right ovary
of here's another male model
therefore what is this endocrine gland
the answer to that is a left testicle
and if I pull this piece off
here's the right testicle
and I think we've pretty much quizzed you on everything.
As always if you have any questions, please feel free to leave them in the comments down below
and thank you once again for watching :)
