superficial perineal space in men includes
ischiocavernosus, bulbospongiosus, superficial transverse perineus mm, and crura & bulb of penis
ischiocavernosus, function
compresses venous outflow to maintain erection
bulbospongiosus, function
empties urethra & compresses deep dorsal vein & erectile tissue
superficial transverse perineus, function
stabilizes other muscles
penis contains paired
corpus cavernosum
corpi cavernosum are continuous with
penis contains unpaired
corpus spongiosum
corpus spongiosum contains
urethra, which is continuous with bulb & glans
tunica albuginea is
connective tissue capsule around penis
deep aa to penis lie
within corpora cavernosa to supply erectile tissue
dorsal aa course on
dorsum of penis
veins of penis
superficial dorsal v and deep dorsal v
superficial dorsal v of penis drains to

great saphenous v
deep dorsal v of penis drains to
prostatic plexus
glans of penis drains to ______ lymph nodes
DEEP inguinal lymph nodes
common site of injury to penis is in
superficial space
injury to superficial space causes
urine to collect in penis, scrotum & up into abdominal wall
injury to superficial space does not cause spread of urine to
anal triangle or thigh, due to fascial attachments
fascia that allow for the spread of urine in superficial space injuries
Colles' fascia, dartos fascia, Scarpa's fascia
superficial space in women contains
Bartholin's gland, crus of clitoris, & vestibular bulb

pudendal canal lies within
fascia of obturator internus
ischioanal fossa, superior (apex)
levator ani joins fascia of obturator internus
ischioanal fossa, inferior (base)
ischioanal fossa, posterior
ischioanal fossa, anterior
extends into UG triangle as recess

lesser sciatic foramen
pudendal n. courses in
pudendal canal within fascia of obturator internus
pudendal n., branches
inferior rectal n., perineal n., dorsal n. of penis or clitoris
pudendal n. innervates all muscles of
some nn in perineum are not affected by
pudendal n block
ilioinguinal n. supplies
anterior labia & skin around root of clitoris
posterior femoral cutaneous n. innervates
posterior portion of labia
ilioinguinal n. arises from
posterior femoral cutaneous n. arises from
