So now let's have a look at the female.
The deep and superficial pouches within
the female. And we can see these on this
diagram here. We can see we have the perineal
membrane over on this side we can see it here.
And we can see the perineal
membrane on this side.
What we can see if we start with
the superficial perineal pouch
this is the superior aspect with the
pubic symphysis and I have inferior down here
ischial tuberosities. So
we have got the posterior
border of the perineal membrane here.
We can see that in the superficial perineal
pouch of the female we have similar structures.
We have the ischiocavernosus muscle
and that ischiocavernosus muscle
is going to be covering the crus
instead of the corpus cavernosa
but the crus of the clitoris.
And that is very similar in orientation
to the corpus cavernosum in the male.
And again its covered by the ischiocavernosus
muscle and these are coming up
again from the ischiopubic ramus in
this direction to unite in the midline.
and here we find the corpus
cavernosum of the clitoris.
We can see we have the perineal membrane
where these are attached. And in the midline
we have in the female the vagina
which opens up into the vestibules.
Obviously in the male without the vagina,
this is closed. We don't have an opening.
But in the female, for the
vagina we have this opening.
and its flanked on either side
by the bulb of the vestibule.
And again this is a erectile
tissue. The bulb of the vestibule
flanks the opening to the vagina.
Flanks the vaginal orifice here.
We can see more anteriorly we have the
external urethral orifice here.
So we can see the urethral orifice.
We can see the opening for the vagina
and then we can see the anus. But covering
the bulb of the vestibules which flanks
the lateral aspects of the opening to the
vagina we find we have bulbospongiosus muscle.
So analogous structures for
both the male and the female.
If we were to take these components of
the superficial perineal pouch away
we then be left with the perineal membrane.
And then we can see the opening
for the vagina here. And then we
can see the female urethra
and surrounding it we have got
the external urethral sphincter.
If we were to see the deep perineal pouch,
then like we did in the male previously
we would have to pull
this membrane away.
Now located within the deep
perineal pouch within the
female, we have our urethra. We have
the external urethral sphincter.
We have deep transverse perineal muscles
and we have parts of the vagina.
And then in the superficial perinal pouch, like
I have just explained, We still have the urethra.
Its passing all the way out
to the external environment.
We now have the superficial
transverse perineal muscle.
We have the root of the clitoris. Just
like in the male we have the root of the penis.
And here we can see we have two crura
covered by the ischiocavernosus muscle.
And then these go on
to form the clitoris.
We have the bulb of the vestibule that's
flanking the vagina. These are covered by
In the female and within the
superficial perineal pouch
we also have the greater vestibular glands
and these help to lubricate the vagina.
We can see these are located in
the superficial perineal pouch.
So here we can see a view
of the female perineum.
If we were looking at externally
these are very similar views so we have
the superior aspect up here. The pubic symphysis
would be deep to the mons pubis here.
And here we have got the more posterior
aspect here and here. And we can see
in these two views that we have the anal
opening here. We have the anal opening
here we can see the anal opening. We have the coccyx
backgroud here. Just like we can see the coccyx
here. And then more anteriorly
we can see we have the
labia major more laterally.
Then we have the labia minor
And then we have the opening for
the urethra and the opening
for the vagina. And this region
would be the vestibule.
If we look, take away the skin, we can see
where we have the glans clitoris. Here
would be the glans clitoris around about
here in diagram. Here we
have the opening for the
urethra and here we have
the opening for the vagina.
And here we can see the bulbospongiosus
muscle covering the bulb of the vestibule.
To find the bulb of the vestibule we
have to clear away this fatty labium
and if you dig down deep. You
should be able to find it.
Another view of the female perineum
here and we can see that's
similar to the male picture we showed. We
had a section, a coronal section, down
through the pelvis. Again we can see the
levator ani muscles, we can see them here.
We can see the vagina and then we can see
the uterus here. We can see the bladder
which is anterior, remember, to the uterus
and to the vagina. And here we have the
urethra and that is positioned anterior to
the vagina which we can see it here.
Now flanking either side of the vagina.
We can see we have bulbospongiosus muscle
and we have the bulb of the vestibule. And these
are hanging from the perineal membrane.
And once again above the perineal membrane we can
see the deep perineal space we can see it here
containing the deep perineal transverse muscle.
And then superficial to
the perinal membrane
we can see the superficial perineal
space. We can see it here
containing those erectile tissues we can also see we
have got the greater vestibular gland here as well.
So similar diagram to
what we saw in the male.
I am trying to explore the
boundaries of the perineum.
