Structure
The superficial perineal pouch is an open compartment, due to the fact that anteriorly, the space communicates freely with the potential space lying between the superficial fascia of the anterior abdominal wall and the anterior abdominal muscles:
- its inferior border is the fascia of Colles, the deeper membranous layer of the superficial perineal fascia that covers the inferior border of the muscles of the superficial perineal pouch. (The fascia of perineum is a deep fascia that covers the superficial perineal muscles individually).
- its superior border is the perineal membrane (inferior fascia of the urogenital diaphragm).

gollark: Mine is just somewhat old.
gollark: Yes, they're fairly competitive now I think.
gollark: Its main advantage is just that it is conveniently usable one-handed or while standing up, which the phone plus keyboard is not.
gollark: Compared to my laptop, my phone has significantly worse CPU power, massively worse GPU power, a smaller but equal-resolution and better-color-calibrated screen, much worse IO (a single USB 2 USB-C port versus five USB ports, a headphone jack, Ethernet, DP/HDMI, and power), much better battery life but worse battery capacity, and worse software.
gollark: 7" is a small tablet or very large phone.
