So now let's turn to the
superficial pouch in the male.
The superficial perineal pouch in the male
we can see here. How we would know if it
is the superficial perineal pouch?
Because here we have
got the perineal membrane.
We can see the perineal
membrane here. This is anteriorly.
This is posteriorly. We have got the anus
here external anal sphincter. We have got that
diamond shape in created pubic
symphysis deep here. So it is going up
in that direction. But we have got our
diamond. We have got our anal triangle here.
Urogenital triangle would
be up in this direction.
So this is going to be the posterior
margin of the perineal membrane.
We can see the perineal membrane here. On this
side we have a window into the deep perineal pouch
because we can see the deep transverse
perineal muscle and bulbourethral glands here.
And the perineal membrane
is sitting underneath.
Attached to the perineal membrane
we have this muscle, bulbospongiosus.
And that's surrounding the
corpus spongiosus of the penis.
Radiating away form the lateral
aspect of the perineal membrane
and coming from the ischiopubic ramus
we have the ischiocavernosus
muscle which is surrounding
corpus cavernosum and these
muscles are really important.
Within the male superficial
we have the superficial transverse
perineal muscle see them here and here
attached to the superficial
surface of the perineal membrane.
We have the root of the
penis which we can see here
covered by their associated musculature.
Here is the root of the penis.
The beginning of the corpus spongiosum
covered by bulbous spongiosous muscle.
Here we have the crus
of the corpus cavernosa
covered by their muscle ischiocavernosus
and they are running in this way.
These will all form, they will
all aggregate in the midline
to form that cylindrical
penis which contains urethra
and the erectile tissues.
We can see that in
a different view now.
Here we can see where we have made a
coronal section down through the pelvis.
We are looking at it from the posterior
aspect. Se we can see superior here
inferior down here. We have
got the apex of the bladder.
We have got the seminal vesicles
here. We have got the prostrate
and in this side it's been opened up.
So what can we see? We can see we have
got levator ani running down here.
We can see we have got the
obturator internus. We have got the
pudendal neurovascular bundle. We can
see we have got the ischioanal fossa
or in this region because its the
level of the perineal membrane.
We can see that we will have the
anterior recess, the anterior recess.
We can see that we have
this deep perineal pouch here.
Deep perineal pouch and this here
we can see is the perineal membrane.
Perineal membrane; sitting on top of it we will
have the deep perineal space with the deep
transverse perineal muscle. We can
also see the bulbo-urethral glands.
So we can see these sitting
within the deep perineal pouch.
In the midline in-line with the urethra we
will also see the external urethral sphincter.
We then have the perineal membrane.
Superficial to the perineal membrane
we now find we have the crus of the penis
and we have the bulb of the penis.
These two making the root. We can
see surrounding the crus of the penis
this erecticle tissue we have ischiocavernosus
and surrounding the bulb of the penis,
we have bulbospongiosus.
And these are located within
the superficial perineal space.
