Pelvic splanchnics
Pudendal
```
Pelvic Splanchnics
28

In order to perform an episiotomy prior to childbirth, the perineum must be anesthetized. By inserting a finger in the vagina and pressing laterally, what palpable bony landmark can be used as the posterior limit of the pudendal canal?
Coccyx
Ischial tuberosity
Ischiopubic ramus
Obturator groove
Ischial spine
```
Ischial Spine
-The pudendal canal travels from the lesser sciatic foramen to the deep transverse perineus muscle. The ischial spine marks the posterior limit of the pudendal canal, so that's the correct answer. If you weren't sure about that, you might also notice that the physician here is trying to perform a transvaginal pudendal nerve block. This means that the physician will be using the ischial spine as a landmark and inserting the needle near this prominence, coating the pudendal nerve with anesthesia before it gives off its branches.
29
```

The rectouterine pouch is the lowest extent of the female peritoneal cavity. At its lowest, it provides a coat of peritoneum to a portion of the:
urinary bladder

vagina
```
VAGINA
In females, the rectouterine pouch is a peritoneal fold reflecting from the rectum to the posterior fornix of the vagina. At its lowest extent, the rectouterine fold is draped over the posterior fornix of the vagina. This means that surgeons can make an incision in the posterior fornix of the vagina and enter the rectouterine pouch to harvest eggs from the ovaries or remove an ectopic pregnancy. Take a look at Netter Plate 337 for a picture of this relationship
