Mnemonics – Pelvis/Perineum
LH vs FSH: function in male
LH: Leydig cells stimulated to produce testosterone.
FSH: Spermatogenesis stimulated.
Urination: autonomic control
"When you pee, it's PISs":
Parasympathetic Inhibits Sympathetic.
Spermatic cord contents
"Piles Don't Contribute To A Good Sex Life":
Pampiniform plexus
Ductus deferens
Cremasteric artery
Testicular artery
Artery of the ductus deferens
Genital branch of the genitofemoral nerve
Sympathetic nerve fibers
Lymphatic vessels
Spermatic cord contents
"3 arteries, 3 nerves, 3 other things":
3 arteries: testicular, ductus deferens, cremasteric.
3 nerves: genital branch of the genitofemoral, cremasteric,
autonomics.
3 other things: ductus deferens, pampiniform plexus, lymphatics.
· Note some argument about this: Moore doesn't put in
cremasteric nerve, Lumley puts in inguinal...
Anteflexed vs. anteverted: what bodypart each describes
"Anteflexed and Anteverted both bend toward Anterior".
· The "V" words go together: Verted is for the cerVix (therefore
flexed must be uterus).
Branches of Internal Iliac Artery
, "I Love Going Places In My Very Own Underwear":
Ileolumbar
Lateral sacral
Gluteal (superior and inferior)
Pudendal (internal)
Inferior vesicle (uterine in females)
Middle rectal
Vaginal
Obturator
Umbilical
Ureter to ovarian/testicular artery relation
"Water under the bridge":
The ureters (which carry water), are posterior to the
ovarian/testicular artery.
· Clinically important, since a common surgical error is to cut
ureter instead of ovarian artery when removing uterus.
Pelvis: sacral innervation
"S2,3,4 keeps the 3 P's off the floor (Penis, Poo, and Pee).
· S2,3,4 innervates the anal sphincter, urethral sphicter, and
causes erection.
Sperm pathway through male reproductive tract
"STaRT DEEP--VD!":
· Sperm duct system progression, from smallest to largest:
ST: Seminiferous Tubules
RT: Rete Testes
DE: Ductus Efferentes
EP: Epididymis
VD: Vas Deferens
Obturator canal: relations of structures
"Who's flying in the top of Obturator canal? Obviously Not A
Vein!":
Obturator
Nerve
Artery
Vein
Female pelvic organs' blood supply
"3 organs, each get 2 blood supplies":
Uterus: uterine, vaginal.
Rectum: middle rectal, inferior rectal [inferior rectal is the end of

Bladder: superior vesical, inferior vesical.
