What are the two pouches in the urogenital triangle?
superficial perineal pouch and deep perineal pouch
When the membranous layer of the superficial fascia passes into the perineum, what does it become, and to what is it attached?
' attaches to ischiopubic ramus and is called Colles fascia
Camper's fascia forms what in the perineum?
Fat of mons pubis and fat of labia majora
Immediately under the Colles facia is what pouch?
Superficial perineal pouch
Scarpa's fascia fuses with what to become Colles fascia?
fascia lata of thigh
The Dartos Muscle is formed from what?
Campers fascia that lost its fat
The superficial perineal pouch lies between what two layers?
inferior fascia of the UG diaphragm (perineal membrane) and membranous layer of the superficial perineal fascia (Colles' fascia)
Colles' fascia forms which boundary of the superficial perineal pouch?
inferior
List the contents of the superficial perineal pouch.
superficial transverse perineal muscle, ischiocavernosus muscles and crus of the penis/clit, bulbospongiosus muscles and bulb of the penis/vestibule, central tendon of the perineum, greater vestibular glands, internal pudendal vessels, perineal nerve and its branches
With what other structures is Colles' fascia continuous?
Scarpa's fascia of the anterior abdominal wall, dartos tunic of the scrotum, superficial fascia of the penis
The inferior fascia of the urogenital diaphragm is also known as what?
Perineal membrane
What are the muscles of the superficial perineal pouch?
ischiocavernosus, bulbospongiosus, supervicial transverse perineal
From where does the ischiocavernosus originate?
ischial tuberosities and ischiopubic rami
Where does the ischiocavernosus insert?
corpus cavernosum (crus of penis or clitoris)
What is the innervation of the ischiocavernosus muscle?
perineal branch of pudendal nerve
What is the function of the ischiocavernosus muscle?
maintains erection by compressing the crus and deep dorsal vein, thereby retarding venous return
From where does the bulbospongiosus muscle originate?
perineal body
Where does the bulbospongiosus muscle insert?
corpus spongiosum and perineal membrane in males and pubic arch and dorsum of clit in females
What is the innervation of the bulbospongiosus muscle?
perineal branch of pudendal nerve
From where does the superficial transverse perineal muscle originate?
ischial rami and tuberosities
Where does the superficial transverse perineal muscle insert?
perineal body
What is the homologue of the bulbourethral gland in the female?
Greater vestibular (Bartholin's) glands
Where are Bartholin's glands located?
in the superficial perineal pouch, deep to the vestibular bulbs in the female
What are the superior and inferior boundaries of the deep perineal space?
superior fascia of the UG diaphragm, inferior fascia of the UG diaphragm (perineal membrane)
What are the contents of the deep perineal pouch?
deep transverse perineal muscle and sphincter urethrae, membranous part of the urethra, bulbourethral glands, branches of the internal pudendal vessels, dorsal nerve of penis & perineal nerves
From where does the deep transverse perineal muscle originate?
inner surface of the ischial rami
Where does the deep trasnverse perineal muscle insert?
medial tendinous raphe and the perineal body
What is the innervation of the deep transvers perineal muscle?
perineal branches of the pudendal nerve
From where does the sphincter urethrae originate?
inferior pubic ramus
Where does the sphincter urethrae insert?
median raphe and perineal body
What innervates the sphincter urethrae?
perineal branch of the pudendal nerve
What are the components of the urogenital diaphragm?
deep transverse perineal muscle and sphincter urethrae, invested by superior and inferior fascia
What part of the male urethra pierces the UG diaphragm?
membranous
To what does the root of the penis attach and by what structure?
to the pubic symphisis by suspensory ligament
From where does the fundiform ligament of the penis arise?
from the linea alba and the membranous layer of the superficial fascia of the abdomen (Scarpa's)
The suspensory ligament of the penis (or clitoris) inserts where, and what is its relation to the fundiform ligament?
inserts into the deep fascia of the penis or into the body of the clit, lies deep to the fundiform ligament
The tunica albuginea is more elastic around which part of the penis?
corpus spongiosum
From where does the scrotum receive blood supply?
external pudendal arteries and posterior scrotal branches of internal pudendal arteries
What is the innervation of the scrotum?
anterior scrotal branch of the ilioinguinal nerve, genital branch of the genitofemoral nerve, posterior scrotal branch of the perineal branch of the pudendal nerve, and the perineal branch of the posterior femoral cutaneous nerve
What structures are considered part of the root of the penis?
two crura and the bulb
The labia majora are terminations of what?
round ligaments of the uterus
Into what does the superficial dorsal vein of the penis drain and into what does that drain?
superficial external pudendal which drains into the great saphenous vein
Into what does the deep dorsal vein of the penis drain?
Prostatic venous plexus
The dorsal arter of the penis and deep artery of the penis and artery to the bulb are branches of what artery?
internal pudendal
Where does lymph from the skin of the penis drain?
superficial inguinal lymph nodes
Where does lymph from the corpus cavernosum drain?
internal iliac lymph nodes
Into which lymph nodes does lymph from the corpus spongiosum drain?
internal iliac
The distal urethra and glans of the penis drain into what lymph nodes?
deep inguinal and external iliac lymph nodes
What pierces the UG diaphragm in males and females, respectively?
urethra in males, vagina in females
What is the nerve supply of the anterior part of the vulva?
ilioinguinal nerve and genital branch of the genitofemoral nerve
