to sit on that floor. So as I mentioned, the
popliteal fossa contains all of the neurovascular
structures that pass from the thigh to the
leg. It contains the small saphenous vein
as it pierces the popliteal fascia and enters
into the popliteal vein. So here we can see
the small saphenous vein that?s going to
pass all the way up. We?ve cut it here to
show, but we can then see it passing into
the popliteal vein. See the popliteal vein
here. We can also see an opening for the small
saphenous vein just there. We can see we?ve
got the popliteal artery and its associated
branches, some important genicular branches
that go and supply the knee joint. We can
see the tibial and the common fibular nerves,
the tibial nerve passing straight down, the
common fibular nerve forming part of the
superolateral border. We can see the posterior cutaneous
nerve of the thigh running down in this region.

We can see popliteal lymph nodes, and it?s
going to be full of fat. So in this lecture,
we?ve looked at the gluteal region, we?ve
looked at the muscles that make up the mass
of the bulk of the gluteal region, gluteus
maximus, gluteus medius, gluteus minimus,
piriformis, gemelli, obturator internus, and
quadratus femoris. And then we used piriformis
as a landmark to look at some important neurovascular
relations. We then quickly looked at the thigh
in cross-section, the fasciae latae and how
the intermuscular septae separated the thigh
into anterior, posterior, and medial compartments.
We then looked at the posterior thigh. We
looked at the hamstrings, and we looked at
biceps femoris, and also very briefly, the
neurovascular relations. The popliteal fossa,
we looked at the boundaries, the roof, the
floor, and we just finished off by looking
at the contents of this space.
