Male repro Flashcards
Blood supply to the penis
3 branches of the internal pudenal
what are the 3 branches of the pudendal which go onto supply the penis
dorsal artery of penis
deep artery of penis
bulbourethral
what is the blood supply to the testes
paired testicular arteries from the abdo aorta
what do the 2 paired testicular arteries anastomose with
the cremasteric artery and the vas deferens artery
what is the blood supply to the anterior scrotum
external pudendal
what is the blood supply to the posterior scrotum
internal pudendal
what is the blood supply to the prostate
prostatic artery which is a branch of the internal pudendal
Blood supply to the seminal vesicle
inferior vesicular, internal pudendal and middle rectal which branches off the internal iliac
Blood supply to the bulbo urethral gland
bulb of penis artery
cavernous space of penis drained by
deep dorsal vein which part of the prostatic venous plexus
skin and cutaneous tissue of the penis drained by
superficial dorsal vein
what plexus drains the testes before it drains into the testicular vein
pampiniform plexus
where does the right testes drain into
inferior vena cava
where does the left testes drain into
left renal
where doe the prostate drain into
prostatic venous plexus which drains into the internal iliac and intervertebral plexus
what is the lymph drainage of testes
lumbar and para aortic nodes
what is the lymph drainage of the scrotum
superficial inguinal nodes
what is the lymph drainage of the seminal vesicle
external and internal iliac nodes
what is the lymph drainage of the bulbo urethral glands
external and internal iliac nodes
what are the 3 parts of the penis
root body and glands
where do the left and right crura attach
ischial ramus
what is the crura covered by ie which muscle
ischocavernosal
which muscles contract to empty the spongy urethra of residual semen and urine
bulbospongiosus x2
the anterior fibres of which muscle also help to maintain an errection
bulbospongisousm
what do the crura carry on to become in the body of the penis
corpora cavernosa
which muscle pushes blood to maintain and errection
2xischiocavernosa
which part of the penis continues from the root to the glands penis
the corpus spongiosum as it contains the urethra
what is the frenulum
the banjo string
what is the medical term for the foreskin
prepuce
which fascia holds all 3 connective tissue of the penis together
deep (bucks) fascia
what is the nickname for the most external fascia
colles
where does the suspensory ligament go to and from
erectile bodies to the pubic smyphsis
what is the fundiform
the sling that attaches to the pubic symphhysis
where were the testes originally located in development
the posterior abdo wall but descends down through the inguinal canal
where does sperm travel in the testis
seminiferous tubule, rete teste, epididymis
what is the tunica abulginea
it travels into the testicle between the seminiferous tubules
what is the tunica vaginalis
it covers the testes
where does the vas deferens travel between
the epididymis to the ampulla
tell me about the route of the spermatic chord
it starts at the deep ring, passes down to the superifical ring and at that point goes down into the scrotum
where is the deep iloinguinal ring sitated
half way between the ASIS and the pubic terbercule
where is the superficial ilioinguinal ring situated
next to the pubic terbercule
where is the inguinal canal
between the deep and superficial rings
where is the seminal vesicle located
between the bladder and the rectum
what makes up the ejaculatory duct
the vas deferens and the seminal vesicle duct
what do the first fractions of the seminal vesicle produce
spermatozoa and prostatic secretions
what is the remaining volume of seminal vesicle secretions made up of
testicular spermatozoa, prostatic secretions and mucus from the bulbourethral glands
what things are in the prostatic secretions from the seminal vescicle
alkali fluid
fructose
prostaglandins
clotting factor
what does the prostate secrete and why
proteolytic enzymes into the semen to break down the clotting factors so remains a fluid
where does the enzymes from the prostate leave the prostate
via prostatic ducts that open into the prostatic part of the urethra immediately before ejaculation
what is contained in the central zone of the prostate and what percentage of the overall prostate is this zone
ejaculatory duct and 25%
what is contained in the transitional zone of the prostate and what percentage of the overall prostate is this zone
urethra and 5-10%
what is contained in the peripheral zone of the prostate and what percentage of the overall prostate is this zone
65% and is the main body
how would you describe the bulbourethral gland
a pea shaped exocrine gland
what is the function of the bulbourethral gland
secretes lubricating mucus secretions
where is the bulbourethral gland found
in the deep perineal pouch superior to the bulb of penis
where does the bulbourethral gland open into
proximal portion of the spongy urethra
what are the 3 parts to the male urethra
prostatic, membranous and penile bulbous
what muscle covers the spermatic chord
cremaster
the vas deferens passes through the inguinal canal and then posteriorly to which artery
inferior epigastric artery
before the vas deferens combines with the seminal vesicle what does the vas deferens pass anteriorly to
the ureter
what is the mnemonic for the layers of the scrotum from superficial to deep
Some Damn Englishman Called It The Testis
what are the layers of the scrotum from superficial to deep
skin dartos muscle external spermatic fascia cremasteric fascia internal spermatic fascia tunica vaginalis tunica albugina
contents of the spermatic chord: 3 arteries
testicular, ductus deferens, cremasteric
contents of the spermatic chord: 3 veins
genital branch of the genito femoral, cremasteric and autonomic
contents of the spermatic chord: 3 other things
vas deferens
lymphatics
pampniform plexus
