    In this lecture, we are going to look at the bony pelvis and the pelvic floor. So, we will look at the various key landmarks within the bony pelvis that are important for the future muscle attachments that we are going to talk about. We will also look at some important sex differences between the male and female. We will look at the boundaries, the pelvic walls within the bony pelvis and then we will spend some time looking at the muscles that form the pelvic floor, levator ani and coccygeus and then we will look at the function of those muscles and why they are so important. So, let's have a look at the bony pelvis, first of all and we have looked at the various parts of this before, but it’s a good opportunity to review this as we will need to remember these structures as we move through this lecture and the next. So, here, we can see we have the anterior view of the pelvis and here, we can see we have a superior view looking down into the pelvis. And we can see we have numerous structures in the midline. We have the pubic symphysis that is joining the two pubic bones together. So, we have the pubic bone here and here. Specifically, we have the superior pubic rami and we have them here and here and here, we have the inferior pubic ramus. We have the two inferior pubic rami, left and right sides here. We can also see that we have the pelvic brim. We can see that over on this side. And then we have the pelvic brim running around in this direction and we have the sacral promontory here. Pubic symphysis, again, pubic crest forming parts of the superior pubic ramus...
