Where is the pelvis located in the body
Bones of the Pelvis | Pelvic Anatomy
hey everyone it's sarah with registered
nurse orange comm and in this video
we're going to go over the bones of the
pelvis and skinny bones Jones is going
to graciously help us with this task so
for your anatomy and physiology class
you may be required to know all these
little bones of the pelvis so in this
video I'm going to go over those for you
and then after you watch the video be
sure to go to my website registered
nurse orange comm and take the quiz
about the pelvis bones and a link should
be popping up so you can click that and
take that after you watch this video so
let's get started okay we have skinny
bones Jones's pelvic region right here
and your pelvic region it houses your
reproductive organs and the end of the
digestive system and the pelvic is where
your femur which is this big bone which
is the largest bone in the body meets
and the acetabulum and forms the upper
part of the leg now the pelvic region
can be divided into eight parts and I
like to think of it these eight parts
because everything else fits along if
you know these key eight parts which
we're going to go in detail but let me
go over them real fast we have the
sacrum which is back here you have the
ilium you have the ischium you have the
pubic bone the pubic synthesis the
acetabulum which is this little socket
in here the obturator foramen and in the
coccyx bone which is the tailbone now
first let's go over the ilium the ilium
is located right here and this is the
largest bone of the pelvis and from the
ilium you have what's called an iliac
crest and on this crest you have the
posterior let me turn him around for you
you have the posterior superior iliac
spine you remember that because
posterior means back superior means up
so there's the spine of iliac crest and
then you have the anterior superior
iliac spine which is right here and what
happens with these is that muscles and
ligaments attach to these areas and
lax spine like I said has four
attachment points and they are the
anterior superior iliac spine the
anterior inferior iliac spine the
posterior superior and the posterior
inferior so there's four points where
these muscles and ligaments attach now
after that you have what's called the
sacrum iliac joint and this is right
here between the sacrum and the ilium of
the pelvis now it's this little crease
right here and what this is it's a joint
it's a very strong joint and it helps
you with weight bearing it's very
important with that and after that we
have the acetabulum which if this
skeletons little femur was removed you
would see a nice little socket right in
there and it's just like a little hole
where your femur head fits into and it
allows you to move your hip and it's a
socket bone then you have the pubis and
the pubis is this bone right here it's
below the ilium and your pubis is
function it forms part of the acetabulum
the in the hip joint and it provides
protection to organs such as the urinary
organs and the reproductive organs and
located below the pubis is called the
obturator foramen it's this hole right
here now remember this by foramen the
word foramen means a hole opening into a
bone so whenever you see that think of
that and obturator foramen is created by
the ischium which will go over here in a
second and the pubis and it allows
nerves and blood vessels to pass through
here and below that is the ischium and
this forms the lower and back part of
the hip bone and it's this little area
right below that and it's situated
behind the pubis and it just bends back
a little bit then in the middle of this
you have what's called the pubis
synthesis and this is a joint it's made
of
cartlidge and what the function of this
little thing is is it absorbs shock
during walking and in women it allows
the woman to deliver the baby whenever
the baby is coming down through the
pelvic canal and last but not least we
have the pubic tubercle and what this is
it's just this little notch right here
and remember tubercle is an area that's
small and rounded projection and what it
does is it allows the egg renal ligament
to attach to it so you're in Guino
ligaments there and just remember on the
body you know how you have the Guino
area it's located on your body in that
and just remember that the guina
ligament will attach to that part so
that's the big thing about that now that
is everything about the pelvis and I
hope that helped you out and that was
just a quick overview okay there you
have it that was the bones of the pelvis
now go to my website register nurse or
in comm and take the quiz and see how
well you understood that material and
thank you so much for watching and

videos for anatomy and physiology
