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


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
