So let's have a look.
The male perineum, its deep pouch.
Now we have looked at this previously. We have
looked at this diagram which we can see
when we looked at the male reproductive organs.
We have got the bladder. We have got the prostrate.
The deep perineal pouch is going to form
somewhere where the prostrate is here
and where we can see this membranous urethra
that's passing through. All of this
is going to be in the superficial
perineal pouch and here we have the deep
perineal pouch. Remember we have the levator ani
running down in here. So if we
look at the cartoon on this side
we can see that we have
this urogenital triangle.
This urogenital triangle and what
we have got here is this deep
transverse perineal muscle. This
deep transverse perineal muscle
and that is sitting on
this perineal membrane.
Look at this little clip here is
reflecting the perineal membrane.
So the perineal membrane would be all the
way over here. But we have reflected here
so look into the perineal pouch.
And what we find in the deep perineal pouch,
we find the external urethral sphincter.
We find the bulbourethral
glands, we can see these here.
We find the deep transverse perineal muscle
all located within the
deep perineal pouch.
We then have the perineal membrane
which is going to sit over here.
can then sit on top.
So we looked at this in the
table in the previous few slides.
But it's worth repeating myself.
We are looking at the
looking at the urogenital triangle
and within the urogenital triangle
we have the perineal membrane.
And we can see it's been reflected to
open up the deep perineal pouch.
Contains the deep transverse
perineal muscle we can see here.
External urethral sphincter surrounding it.
Bulbourethral glands we can see them here
and various vessels and nerves. All
within the deep perineal pouch of the male.
If we just look at the penis
that is then continuing through
the perineum within the
superficial perineal pouch.
Then we can see that we have a whole number
of what's known as erectile tissues.
Known as the erectile tissues. We can
see if we have a transverse section
through the penis, here we have
the dorsal aspect of the penis.
and here we have the
ventral aspect of the penis.
We can see that we have these
large erectile tissues, see them here,
and see them surrounding
the urethra. Here we have the
urethra (the spongy urethra)
which we can see here.
Surrounding them we have the corpus
spongiosum and positioned more dorsally,
we have this erectile tissue
which is the corpus cavernosum.
These are important when the
penis becomes engorged during
sexual activity where
we develop an erection.
And these becoming gorged with the
blood as they fill up like sponges.
And we can see we have the urethra
surrounded by the corpus spongiosum
and we have the corpus cavernosum
here within the penis
these two erectile tissues. The
penis itself consists of the root
the body and the glands. The root of the
penis which we will come to in a moment
is attached to the underside
of the perineal membrane.
So this is located within
the superficial perineal pouch.
We can see the root of the penis coming
here. Here we have got the bulbourethral.
So this is a separation between the deep
perineal pouch and superficial perineal pouch.
Here we can see we have the corpus
cavernosum, these erectile tissues
and urethra passing through.
The bulb and what's known as the crus
are attached to the inferior surface
of the perineal membrane
and that forms this root.
You will see those in a moment.
The bulb and the crus are
covered by some muscles
and these are again within the superficial
perineal pouch known as bulbospongiosus
