Okay, now let's
turn to the perineal pouches.
The perineal pouches are found
within the urogenital triangle.
And within the urogenital triangle
we have the perineal membrane.
And that separates the perineum
into these deep and superficial
perineal pouches. If we look
at the deep perineal pouch
that is bounded inferiorly by the
perineal membrane and superiorly
it contains the anterior
recesses of the ischioanal fossa.
Ultimately most superiorly we
would have the levator ani muscles.
It contains the deep perineal pouch.
So everything that is superior
to the perineal membrane,
it contains the deep transverse perineal muscles.
Contains the external urethral sphincter.
Contains the intermediate part of the urethra
in the male. Also in the male it
contains the bulbourethral glands.
and as we will see it contains
important blood vessels and nerves.
The superficial perineal pouch is
everything that's going to be superficial
to the perineal membrane. Everything
that is below the perineal membrane
inferior to the perineal membrane
and ultimately this is going to
be bound by the subcutaneous tissue.
It's going to contain in the male or female
the root of the penis and the citoris.
Its going to contain the urethra. Contain the
superficial transverse perineal muscles.
Superficial to the perineal membrane
contain vessels and nerves
and in the female it contains
the greater vestibular gland.
