    In this lecture we are going to look at the perineum and external genitalia. So we will look at the perineum which is this shallow space inferior or can be considered to be superficial to the pelvis and the pelvic floor. We are going to look at the boundaries and the divisions of the perineum. And specifically we will look at what's called the ischioanal fossa. We will look at its boundaries within the perineum and also its contents. And then we are going to look at the perineal pouches and these can be particularly complicated. The deep and the superficial perineal pouches. And some sex differences we find for the male and the female. And then we will look at the neurovasculture of the perineum and return to the internal pudendal artery. So as I have mentioned at the top, the perineum is a shallow space which is inferior or it can be considered superficial to the pelvis. It contains a number of important structures including muscles and erectile tissues and these are associated with reproduction. So, let's first of all let's just try and orientate ourselves as to where the perineum is located. Now here we can see we have hemisections through the male and the female pelvis. We can see we have male here and other male here and a female. We have three sections through the pelvis. We have anterior here and posterior. Again anterior posterior anterior posterior. You should be familiar with these images by now. And what we can see is here the organs haven't actually been hemisected or the bones of the pelvis have been hemisected. And on this side that have been hemisected directly down the midline. Now what we can do is just draw a simple line that separates the pelvis...
