Inguinal Region Flashcards
Each testicle is surrounded by the thin visceral layer of the ________ and the tough inner ________
tunica vaginalis
tunica albuginea
Where are sperm formed?
seminiferous tubules
After sperm are formed they move through ______ then the _____to the _______
straight tubules
rete testes
efferent ductules
Where are sperm stored in/eventually exit
epididymis
Tail of the epididymus leads into the _______ which carries sperm and eventually semen to the urethra
ductus (vas) defernes
What is the inguinal canal bounded by
the inguinal ligament on the anterolateral side
How many arches does the inguinal canal have and what are they formed by?
3;
transversus abdominus, internal oblique, external oblique
The deep ring is marked by what
transversalis fascia
The superficial ring is marked by what
external oblique fascia
What pulls the testes through the body wall?
gubernaculum (the governor)
Pareital peritoneum becomes
tunica vaginalis
Transversalis fascia becomes
inner spermatic fasica
Internal oblique becomes
cremasteric muscle and fascia (brings testicles in)
external oblique becomes
external spermatic fascia
Scarpa’s fascia becomes
Dartos muscle and fascia
Ductus (vas) deferins
thick muscular tube that carries sperm and semen
Testicular artery
comes off aorta, oxygenates testicles
Cremasteric artery
comes from inferior epigastric a
oxygenates cremaster muscles
ductus deferens a
comes from inferior vesicular a
oxygenates ductus deferens
pampiniform plexus
network formed by ~12 veins that converge superiorly as left or right testicular veins
Function of Dartos muscle
wrinkly balls
Function of cremaster muscle
pulls up scrotum closer to body
_____ branch of genitofemoral nerve innervates the _____ muscle
genital
cremaster
______ accompany the testicular a and the ductus deferens
symphathetics
What does the gubernaculum do in females
pulls ovaries down (but doesn’t go past the pelvic brim)
becomes the ovarian and the round ligament
Difference of cremaster muscle in females
a few short loops of muscle around the round ligament
Where is the round ligament found
in the labia majora (terminates here)
Direct hernia
goes through hasselbach’s triangle
contained by external oblique or pushes through the superficial ring
Indirect hernia
more common in young men
passes through the patent processus vaginalis, alongside spermatic cord
Femoral hernia
below inguinal ligament where the femoral vessels push through
just as common in women as in men
Hydrocele and Hemotocele
serous fluid or blood build up within the tunica vaginalis
Sebaceous cyst
generation of cyst within the epidermis, often related to infection of hair follicle
Spermatocele
cyst within the head of the epididymis
very common
pt may think it’s testicular cancer
Cryptochidism
failure of testes to descend
most descend on their own within a year of birth
monorchidism
one testicle
polyorchidism
more than 2 testicles
ectopic testes
testes deviate from normal path and end up somewhere else
Vasctomy
ductus (vas) deferens is cut and may be tied
Anterior cutaneous branches of iliohypogastric innervate what
ilioinguinal
Anterior scrotal branch of ilioinguinal innervates what
dartos
