scrotum and testes Flashcards
the endocrine function does ___ in the testes and the exocrine function does ___
endo - testosterone
exo - sperm production
the scrotal wall is formed by the ___ muscle
cremaster
Cremaster muscle forms the scrotal wall, then the
tunica vaginalis
The tunica vaginalis layers -
parietal vaginalis is outermost , visceral vaginalis is adhered to testicle
the cavity created by the parietal vaginalis and visceral vaginalis is
cavum vaginale.
The testis is the covered by a denser covering called the
tunica albuginea
Tunica albuginea wraps around ____ to form the ____
posteriorly , mediastinum
this is responsible for what goes in and out of the scrotum
Spermatic cord
Sperm production and transportation all starts with
Seminiferous tubules
Seminiferous tubules –>
straight tubules
straight tubules converge into
rete testis at mediastinum.
this brings the sperm to epididymis
Efferent ducts
The job of the epididymis is
sperm storage and
maturation
carries the sperm
from epididymis up into body to seminal vesicles
Deferent duct or vas deferens
Testicular/gonadal artery (main blood supply) originates at
aorta
Cremasteric and deferential arteries originate from
iliac arteries
pampiniform plexus drains testes then empties into
testicular veins
. Rt testicular vein drains into
IVC
Lt testicular vein drains into
lt renal vein
u/s of scrotum looks homogeneous texture surrounded by
tunica albuginea and
vaginalis
the epi head is __ to testes
superior
the epi head measures
12 mm , 1.2 cm
the epi body runs __ to testes
posterior
the epi tails runs __ to teste
inferior
