this region is particularly tricky. So, we
have got a table here which summarises what
I have... what I have just mentioned and here,
I have, at the top, got the level at which
the inguinal canal is being sectioned to look
at the anterior posterior walls, the roof
and the floor. So, we can see at the level
of the deep ring, we can see the various structures
that are forming those boundaries. We can
see in the middle of the inguinal canal, we
have a whole series of other boundaries and
here, at the level of the superficial inguinal
ring, we can see another series of boundaries.
We can see that most of the time the floor
of the inguinal ligament, the lacuna ligament,
is an extension of the inguinal ligament as
it tapers away. We can pick out other
important structures like the conjoint tendon.
This is the internal oblique and transversus
abdominis muscles combining directly behind
the posterior wall of the superficial inguinal
ring we have the conjoint tendon.
We can see the rest of the posterior wall is made up
of this transversalis fascia. So, this is
a good table that just serves as a reminder
of the various boundaries of those...
of the inguinal canal.
