    Transcript

    00:00 and the posterior division, so let?s have a look.

    00:01 We can see that running down this internal iliac artery here we have an anterior division which we can mark out here and we have a posterior division which we can see here.

    00:14 The anterior division and the posterior division. Now these are going to give rise to numerous parietal and visceral branches.

    00:22 Parietal branches that will go and supply the body wall and visceral branches that will supply the organs.

    00:31 Its important to remember that have these ovarian arteries.

    00:34 And these arteries, remember, are coming from the aorta. And although the ovaries are located within the pelvis, these structures within the pelvis are not supplied by the internal iliac.

    00:47 They are supplied with the ovarian arteries. And these run within the suspensory ligament that we have spoken about and they originate from the abdominal aorta.

    00:57 As we will see, that maybe some anatomoses with the uterine artery.

    01:03 These arteries tend to be paired. We tend to have both of them on the left side and on the right side. And also within the pelvis we can have what are known as the unpaired arteries. And these don't tend to come from the internal iliac artery.

    01:21 What we tend to have is a median sacral artery and that's running directly down from the aorta, so we have the median sacral artery. We can see that running down in this direction.

    01:32 The name median gives it away that it?s an unpaired artery.

    01:36 And we also have a superior rectal artery.

    01:40 The superior rectal artery is the direction continuous of the inferior mesenteric artery into the pelvis.

    01:47 It can divide into numerous branches that will descend either side of the rectum, and anastomose with middle and interior rectal arteries, we will explore later.

    01:58 But its primarily an unpaired artery that comes from the inferior mesenteric.
