In this lecture,
we're going to look at
the cutaneous innervation
venous drainage
and the lymphatics
of the lower limb.
00:09
So let's start off by
looking at the lymphatics.
00:12
And very briefly, there's
just a couple of groups
that you really should
be familiar with.
00:17
These are the superficial
inguinal lymph nodes.
00:21
These are associated really
with the inguinal ligament
that lies superficially
on the junction
between the lower
limb and the abdomen.
00:31
These really are around
about 10 in number
and they follow the course
of the inguinal ligament.
00:37
We also have a series of
deep inguinal lymph nodes,
and there's usually
around three of these
and they run medial
to the femoral vein
and we'll see the position
of the femoral vein
in a little bit more detail.
00:47
But these can be quite
large and quite substantial.
00:49
And they're receiving
a lot of the lymph
that's coming from the deep
structures of the lower limb.
00:55
We also have another
series of deep lymph nodes
and these are really known
as the popliteal lymph nodes.
01:01
They drain both deep
and superficial aspects,
but they're located quite deep
within the popliteal fossa.
01:07
And again, you can dig these out
if you're exploring that region.
