limb. Finally, I just want to talk about the
adductor canal. The adductor canal is a passageway
that allows structures, blood vessels and the
nerve to pass from the anterior compartment
of the thigh to the popliteal fossa. We can,
again here, see on the anterior compartment
of the thigh, we have the femoral artery that’s
passing down alongside the femoral vein, and
we can also see the saphenous nerve. And we
can see that this is just passing deep to
this anteromedial intermuscular septum, this
muscular septum here that’s running from
adductor magnus all the way over to the femur.
So we can see that we’ve got this little
compartment, and this here, is going to be
the adductor canal. We can see the adductor
canal has been opened here, and the contents
of the adductor canal being the femoral artery,
the femoral vein, and this saphenous nerve.
It’s passing out of the adductor canal via
the adductor hiatus. So it’s an aponeurotic
tunnel located within the middle third of
the thigh. It extends from the apex of the femoral
triangle which we can see roundabout here.
Sartorius has been removed, and it extends
to the adductor hiatus of adductor magnus.
It can also be known as the subsartorial canal
as it’s deep to sartorius muscle, and Hunter's
canal after the famous anatomist. The boundaries,
well anteriorly, we have sartorius, and we
have the anteromedial intermuscular septum.
Posteromedially, we have adductor longus and
adductor magnus. And laterally, we have vastus
medialis. But it’s a way that these blood
vessels and nerve can pass through adductor
magnus and enter into the posterior aspect,
specifically, the popliteal fossa. So in this
lecture, we’ve looked at the anterior thigh
muscles. We’ve looked at the quadriceps, as
well as sartorius, iliopsoas, and pectineus.
We’ve looked at their function and innervation.
We then looked at the medial thigh muscles.
We looked at adductor muscles and gracilis.
We also looked at the function and innervation
of them. We then quickly looked at the pes
anserinus and how it’s formed. We looked
at the femoral triangle, its boundaries, and
its content being a femoral nerve, femoral
artery, and femoral vein. And then we looked
at the adductor canal, again, its boundaries
and its contents being the femoral artery,
the femoral vein, and the saphenous nerve.
