Summary

Urogenital Triangle...

Description

Urogenital Triangle Boundaries;

Fascia;  Fatty and membranous  Fatty = Camper’s continuous with ischiorectal fossa and thigh  Males = scrotum Camper’s replaced by dartos smooth muscle  Membranous (Scarpa’s = Colles’) attached to posterior border of urogenital diaphragm, also into labia/scrotum

Urogenital Diaphragm;  Layers fuse anteriorly, leaving a small gap near pubic symphysis  Posterior layers fuse with each other, membranous superficial fascia and the perineal body  ‘Space’ between the layers of the urogenital membrane is called the deep perineal pouch  Transverse perineal muscels; sup. And deep transverse

Deep Perineal Pouch;  Deep perineal pouch between the fascial layers of the urogenital diaphragm  Urethra, sphincter urethrae, deep transverse perineal muscles, internal pudendal vessels and branches  Pudendal (perineal) nerve  Female = vagina, dorsal nerves of clitoris  Male = membranous urethra, dorsal nerves of penis, bulbourethral glands, penile arteries  Bulbourethral glands in M in Deep Pouch; F in Sup.

Superficial Perineal Pouch;  Structures between the perineal membrane (superficial fascia of the urogenital diaphragm) and the skin are in the superficial perineal pouch  Muscles = ischiocavernosus, bulbospongiosus, superficial transverse perineal  Urethra, vagina, clitoris, penis  Erectile tissue = crura, bulb of vestibule (female), bulb of penis (male)  Nerves and vessels

Muscles;

Erectile Tissue;

Perineal Body;  Small fibrous structure  Posterior margin of the urogenital diaphragm  External anal sphincter, bulbospongiosus, superficial transverse perineal muscles all attach here Penis;

Male Urethra;  Pre-prostatic  Prostatic  Membranous

 Penile (spongy)

Clitoris;...
