Anatomy - Male Reproductive System Flashcards
where is sperm made?
seminiferous tubules in testes
what canal does the vas deferens pass through?
inguinal canal
what gland does the vas deferens firstly and secondly pass through?
first - seminal gland
second - prostate gland
once passed through the seminal gland, what is the vas deferens called?
the ejaculatory duct
the ejaculatory duct joins with what to be called the prostatic urethra?
urethra
once in the penis what is the prostatic urethra called?
spongy urethra
what orifice does urine and semen exit?
external urethral orifice
what stores the sperm?
epididymis
what does the testes travel through to get from the abdomen to the scrotum?
inguinal canal
what passes through the inguinal canal when the testes are in the scrotum?
the spermatic cord
what does the spermatic cord consist of?
testicular artery testicular vein vas deferens lymphatic drainage nerves - autonomic and somatic
in the scrotum, what sac does the testis sit within?
tunica vaginalis
what layer of the the tunica vaginalis covers the testis and what layer of the tunica vaginalis covers the scrotum?
faces the testis = visceral tunica vaginalis
faces the scrotum = parietal tunica vaginalis
excess fluid within the tunica vaginalis is called a what?
hydrocele
the spermatic cord contains what 3 things?
vas deferens, testicular artery & pampiniform plexus
testicular torsion refers to twisting of what?
the spermatic cord
the right testicular vein drains into what?
IVC
the left testicular vein drains into what?
left renal vein
what structure does the vas deferens go around?
bladder
what does glandular secretions from the prostate drain into the prostatic urethra through?
prostatic ducts
the prostate gland is shaped like a what?
walnut
inferior to bladder and superior to levator ani
name the part of the prostate that is felt on digital rectal examination
peripheral zone
most prostate cancers arise in these zones
name the posterior parts of the penis that transmit the deep arteries to the penis
(right & left) corpus cavernosum
blood supply:
(a) to the penis
(b) to the scrotum
blood supply:
(a) to the penis - DEEP ARTERIES FROM PUDENDAL FROM IIA
(b) to the scrotum - INTERNAL PUDENDAL FROM EIA
lymph drainage:
(a) scrotum and most of penis
(b) testis
(a) scrotum and most of penis - TO SUPERFICIAL INGUINAL LYMPH NODES
(b) testis - TO LUMBAR LYMPH NODES AROUND ABDOMINAL AORTA
